I had them for 3months and ever since been having problems. We have made sure the holes are adjusted right and they find a place to leak. Sometimes from the holes on the sides or just randomly around the nipples. And..with the 3+ month nipples baby still gets a lot of air in and the nipple pushes in when shes eating. Don't recomend

My exclusively breast fed baby took to this bottle right away! I boiled the bottle and nipple to sterilize and the little one latched right on. Baby has been going back and forth between this bottle and breast without any issues. Thanks to the weeSpring Parent Panel for sending me these bottles!

I loved how smooth the transition was from nursing to using a Chicco NaturalFit bottle. The natural shape and feel of the nipple helped my baby latch on right away. I didn't struggle with nipple confusion like I have had in the past when trying to use a bottle. The bottle comes with two nipple options a straight and angled nipple. My favorite is the angled nipple. This nipple helped prevent getting too much air, which has seemed to help with my baby's gas and spit-up. I also liked the flow of the nipple, which is one of my biggest complaints of other bottle brands. The nipple flow on other brands I have used has been so fast so much milk is wasted. I didn't have to worry about that with this bottle. This bottle would be a great option for a baby that is struggling with acid reflux. I also love that they have also created a glass bottle as another option for parents. Thanks to the weeSpring Parent Panel for letting me try these bottles.

I love the angled nipple - I think it makes it easier to hold for baby. The measurements on the side are easy to read, and it's easy to clean! It feels like a quality product, too. Overall a great product! Thanks to the weeSpring Parent Panel for sending me these bottles!

I am exclusively breastfeeding and wanting to get my baby to take a bottle. I tried this with the hopes of her thinking it was me but she wanted nothing to do with it and couldn't figure out how to latch. I gave it a 3 star rating because I did like the bottle itself. I received these bottles as a gift from the weeSpring Parent Panel.

We love the shape of this bottle. It's comfortable and easy to hold. The tilted nipple makes feeding a squirmy baby a lot simpler. It has leaked occasionally but not a constant problem. Thanks to the weeSpring Parent Panel for sending me these bottles!

My 4 month old son is almost exclusively breastfed but typically gets at least one bottle a day. While I wanted to like this bottle based on the design, it does not seem to be my son's favorite. The nipple is slow flow as advertised but sometimes seems too slow (which frustrates baby at times and prolongs feedings). It can also be difficult to keep the angled nipple full of milk, especially when there is not much milk left in the bottle, which leads to increased air consumption. While this bottle is not for us, I will say that the materials seem to be of good quality and the volume markings are easy to read. I got a chance to try this bottle as part of the weeSpring Parent Panel.

I received these bottles as part of the Wee Spring parent panel, and while I really liked the smaller, 5oz version, I'm not sure an 8oz version is needed. I imagine if you are using these for formula, you may need that size, but in my experience breastfed babies do not take 8oz per feeding, making the capacity and additional size/weight of this bottle unnecessary for the purpose of transitioning between mom and bottle. Otherwise, I was very satisfied with these.

As a first time mom I was nervous about having to transition from breast to bottle and vice versa upon returning to work. With the Natural Fit bottles the transition was seamless. The bottle comes with two nipple options-my little one seemed to take to the angled nipple that closely resembles the breast. No latching issues whatsoever. I, too, prefer this option as it seems that the design helps to eliminate the amount of air baby takes in. (My child is extremely gassy so this was a big factor for us). I will definitely be purchasing this product in the future.Thanks to the WeeSpring Parent Panel for sending me this product to try!

I am an exclusively pumping mama due to some latch issues and have been looking for a bottle that may help her get use to the breast. These bottles have been great for that! We started with the straight nipple to get her use to the flow and feel before moving her to the angled nipple. The angled nipple really mimics the shape of the breast and has helped us latch a bit since transitioning to them which is amazing. I would definitely recommend them to any mama in a similar situation and any who might worry about nipple confusion due to the shape of most bottles. Thanks to the weeSpring Parent Panel for sending me these bottles!

Thanks to the weeSpring Parent Panel for sending me these bottles! They were easy to use and I really liked the design. I don't use bottles often, so not much to compare to, but these worked well for us!

The Natural Fit nipple is an innovation in nipples for bottles. Watching my second daughter latch and use the same mechanics to feed as she does while breastfeeding was reassuring. Overall, the bottle works well and we have had no problems with nipple confusion. I got to test this bottle out thanks to the weeSpring Parent Panel, and I'm glad I did!

With the arrival of our second baby I thought I had this momming thing down. We were going to use the same bottles we did for the first. Well not all babies have the same needs and we learned quickly that the other brand wasnt right for this new little one of ours. These bottles are incredible. I wasnt able to nurse due to a medication i have to take to control seizures so I wanted to give my baby the most natural experience he could get from bottle feeding. These bottles caught my eye because they are made for baby to easily transition from nursing to bottle. I also love the slow flow nipple because it allows my little guy to get the right amount at a time during his feedings because if it were up to him he'd inhale the bottle then throw up. The absolute best thing about this bottle is there are very few parts to wash and after a long day momming the fewer parts to wash the better! Overall, I think these bottles are an excellent choice for anyone!

I received this bottle as part of the weeSpring Parent Panel and was anxious to try it out as I had recently gone back to work and wanted to leave my husband with bottle options to feed our newborn. A nice feature of this bottle is that it does have two different shape nipples, one where the nipple is not centered and mimics a breast nipple and one traditional nipple that is in the center. Having a bottle that you can test out two nipples to me was like buying two bottles for the price of one! There are also different flow nipple options so that the bottle can grow with the infant. These bottles also come in plastic or glass, and the glass bottles have a nice rubber shell that allows for easy grip for myself and as my baby grows, for her to grab on as well. Having tried this out on my baby, the only negative comment I have was that I thought the nipple itself was not long enough and my child had a difficult time latching on.

I love the shape of this bottle. Its wide so it's easier to hold. Great quality! It seals well and seems very well made. I thought my breast fed baby would love it since the nipples of the bottle were made to feel natural. Unfortunately, he had a hard time latching on. He does drink from it, but it sounds like he takes in a lot of air around the nipple. I will definitely keep trying with him and any future babies. Thanks to the weeSpring Parent Panel for sending me these bottles!

I received this bottle as a gift from the Wee Spring parent panel. I love the features and how it closely resembles breastfeeding. My baby took to this bottle very naturally and made the feeding process as simple as ever!

We love the Chicco 8 oz. slow flow bottles! It's easy to fill and easy to clean. Even being a larger size, the bottle is comfortable and light to hold. The nipples are a more natural shape and the angled nipple makes feeding baby easy. We love these Chicco bottles and will definitely recommend them to friends! Thank you to the WeeSpring Parent Panel for sending these to us - they are fantastic!

After two previous breastfed babies who did not take bottles well, we had all but given up hope that we would ever have a baby who took a bottle well. Enter this bottle! Our third took it right away and had no problems switching back to nursing at the end of the day. Not sure if it's the angled nipple that helps or the shape of the bottle, but whatever it is, we have a new go-to! Many thanks to the weeSpring Parent Panel for sending these our way!

The Chicco Natural Fit Bottles are a good choice for transitioning from breast to bottle. I like that there are two nipple options for what suits your baby best. The wide mouth is very convenient when pouring pumped breast milk into it. Thank you weeSpring Parent Panel for the chance to try these out!

I received this bottle along with the natural fit slow flow 5 oz. bottle through the weespring Parent Panel. The only issue I had with this bottle was that the nipple leaked the first time I used it. I switched it out for another nipple and it worked fine so I'm sure it was just a defective nipple. I like that these bottles come in two different sizes because my son eats different amounts at different times in the day. The 5 oz. bottle is perfect for night time because he doesn't eat as much since he just wants to sleep and the 8 oz. is great for during the day because after he wakes up from a nap he is very hungry and finishes a lot more milk. I will definitely continue to use both bottles and am so glad I got the opportunity to test them out.

We received these bottles as a gift from weeSpring Parent Panel and they were a much needed! I had been trying to transition by 2.5 month baby girl to a bottle for when I went back to work and she wouldn't take any! We had already bought several different types of bottle that are promoted for breastfed babies but she didn't like any. I was at the point where I thought it just wouldn't happen when these arrived. My little girl played with it at first but pretty soon she latched onto it and did pretty well. Of course she still likes nursing better but these were a lifesend because now I know I can go back to work and she will still be fed. The breast like nipple helped tremendously in her being able to latch and the flow wasn't as fast as other bottles we tried but instead much more manageable. A must have for breastfed babies who's mommas need to go back to work or just want some "me" time.

I'm so excited that I had the opportunity to try these bottles as part of the WeeSpring Parent Panel. I was exclusively breastfeeding, but now since I have to return back to work I started trying bottles. I've tried other bottles and my baby wouldn't take them, but this bottle was the only one he would take! The 8oz. bottle is perfect for my little ones needs and I couldn't be any happier with a bottle.

Being a first time mom, I was really hesitant to try out any bottle to avoid nipple confusion for my baby. Though a look at the nipple did give me a little confidence of trying it out. I loved the unique angled nipple which made it really close to the breastfeeding. My baby did take a little while to get used to the bottle but there was no nipple confusion and breastfeeding is going on great as well. Thanks to the weeSpring Parent Panel for sending me this bottle!

When we had our fourth I thought we wouldn't need any bottles but the ones we had were glass and heavy. After trying this I can say it is very nice to hold and helps with a natural angle of your wrist. I'm one to think the nipple shape doesn't matter much. However, the angle on this one is actually functional and our fourth used the bottle well. The additional narrow center of the bottle provides a more comfortable grip as well. I would recommend any new parents to start with this bottle first and save yourselves money in troubleshooting for yourself. I had the opportunity to try this bottle as part of the weeSpring Parent Panel and it did not influence my review.

Chicco NaturalFit did the trick in getting my breastfed baby to use a bottle. I liked that the rounded nipple was much wider than the other wide mouth bottles we have tried. It gave my son more silicone nipple area to latch on to. On other nipples his mouth was always over the hard plastic of the bottle. The angled nipple made it much easier to keep air out of nipple. Which has helped a lot, our son doesn't have much gas or spit up than when he was exclusively breastfed. It is now my husband's go to bottle. I received the product complimentary through the weeSpring Parent Panel. The opinions in my review are all my own.

I am a breastfeeding mother. It is convenient to pump and have your baby take a bottle from someone else from time to time for date nights and the like. Two of my three older children have taken bottles and one would not. Now, I am nursing my fourth child and I was hoping that he would adjust and take a bottle. I am glad I tried with this NaturalFit bottle. He latched on right away with the angled nipple! Success! He latched on with the straight nipple too, but it took him a few tries, but it was still less than a minute. I was thankful for the easy transition. I have the plastic and glass bottles. I prefer the glass not because of performance, but just because I feel it is more natural and eco friendly. I would definitely buy this product and recommend it to a friend. I'm glad I was able to try this though as part of the wee spring parent panel!

This has been an awesome bottle for my little man to use. He takes it easier than other bottles I had previously used for my other two children. It is nice having the bonus nipple come with it, but the slanted is my favorite as it resembles more like the breast to me. The bottles themselves are not bulky BUT when using the slanted nipple, I have noticed sometimes water or breast milk will leak a little because the cap is not touching the nipple to close it off. This has only happened when in transit and the bottle has tipped over. It did not make a huge mess but just a slight inconvenience. Thanks to the weeSpring Parent Panel for sending me these bottles!

I got a chance to try these bottles as part of the weeSpring Parent Panel, and am delighted that I did. I almost exclusively breastfeed our new baby, but wanted to introduce a bottle and formula so that he would take a bottle if necessary in the future. This bottle provided a seamless transition for our son. He latched on immediately and drank with no problems. He definitely prefers the slanted nipple, as the straight one tended to collapse in on itself and provided a VERY slow flow, almost to the point of frustration for him. Overall, though, this bottle has been perfect for our baby!

I've always loved Chicco products, but this bottle is my new favorite. I'm breastfeeding my 3 month old and pumping occasionally. The shape and position of the nipple on the Chicco bottle is ideal; my baby transitions back and fourth from the breast to the bottle very easy with this bottle. I also love the nice wide mouth. I can easily set my bottles I used to pump upside down in this bottle to ensure I'm getting every last drop of breast milk. The wide mouth is also very nice if we later transition to formula. I'm glad I was selected to try this bottle as a part of the weeSpring Parent Panel.

I got a chance to try these bottles as part of the weeSpring Parent Panel. Up until then I had been exclusively using another brand. I liked the design of the bottle and it fit better in my hand than the ones I use everyday. I really liked the shape and angle of the nipple. Even though I'm exclusively pumping to bottle feed, the closer to natural the better. My LO had no problem latching on, but I noticed that as she sucked more air was getting into the bottle. Too many air bubbles for my comfort, I noticed less air seemed to get in through the more traditional nipple (bonus) that was included with the bottle. I wanted to love this item but I had to stick to my other bottles or risk a very gassy LO.

I was given the opportunity to try out these bottles as part of the weeSpring Parent Panel, and I was super exited to try them. I primarily breastfeed but I like to get a break every once in a while so having a bottle that promoted ease of switching between the two appealed to me. I first tried the bottle when my son was 5 weeks old with the angled nipple and he wouldn't take it. My husband and mother in law tried as well. We tried a few different times all with the angled nipple and my son wouldn't take it. One day at about 7 weeks I decided to try the regular nipple and he took it right away. He's taken the bottle with the regular nipple a few times since, and goes back and forth between the breast and bottle with ease. I love the design of the bottle it's really smooth and easy to hold. Overall I love the bottle and am really happy with it.

I really like that it's easy for my baby to hold on to. She also seems to really like the sideways nipple shape. She can be very picky about her bottles, being a mostly breastfed baby. I really like that the shape is easy for me to hold, there are a ton of parts to wash, and the grip cover that comes with the glass bottles is awesome. I do have a couple a small negatives. It's a slight annoyance to have to line up the air holes when you put the nipple back on after cleaning. You also have to really make sure to clean under that lip where the nipple screws on. However, like I said, very small negatives. The fact that my baby likes it is good enough for me to put up with them. Thanks to the weeSpring Parent Panel for sending me this bottle!

I primarily breastfeed my son, so when I need to bottle feed (whether I'm out and about or he's in someone else's care) it must be a bottle he will feel comfortable with and these nipples are great. He hasn't had any issues latching. I would definitely recommend. Thank you to the weeSpring Parent Panel for sending me these bottles!

My daughter is 6 weeks old and I am preparing to go back to work, so I needed to find a bottle to transition her from the breast to a bottle. The angled nipple made it easy for my daughter to accept it without any problem! The bottles are easy to clean and easy to hold while feeding. Thanks to the weeSpring Parent Panel for sending me these bottles!

My baby is 7 weeks old and I am getting closer to returning to work, so these bottles have been helpful in the transition from breastfeeding to breastmilk in bottle. The angled nipple works great and makes it easy to hold, and my baby had no issues with latching on, she can drink it down to the last drop! The bottle came with the slow flow nipple, which took some effort for my baby to suck, so I think I will have to try the medium flow nipple to make it easier for her. The bottles are also easy to clean and not too many parts to wash, which makes life a little easier since there are already a lot of other parts to wash with pumping. I'd definitely recommend this bottle - thanks to the weeSpring Parent Panel for sending this bottle for me to try out!

I received these bottles as a gift from the weeSpring Parent Panel and I'm so glad I did! I'm breastfeeding and the nipple on this bottle is perfect for transition back and forth when I'm away. My baby isn't eating over 4oz at this point (only 6 weeks) but once she is this size will be great!

These bottles are great. I loved the angle nipple and the straight nipple. I wasn't sure about the angled nipple at first but my little one didn't seem to mind it at all. We BF so the transition from breast to bottle was no issue. My little one didn't show any signs of gas or extra spit up with these which is great. As for cleaning these bottles they were easy to clean and didn't contain a million parts to clean. The nipples that come with the bottles are 0+mo which is the slow flow, they also make a medium flow 3m+ and fast 6m+. Although we only used the slow flow nipples my son didn't mind but I think I would go out and buy the medium flow nipples in the next week or so. Thanks to the weeSpring Parent Panel for sending me these bottles!

I exclusively breastfed my baby the first 3 months of his life. As an exclusively breastfeeding mom who has returned to work recently and needed to transition to pumping while away from baby, I wanted to find a bottle that would mimic the breast, to make it easier for my little one to transition to while I was at work. I was also looking for a bottle that wouldn't cause any nipple confusion, so that I could still continue to breastfeed my little one when home from work. We tried using the Chicco Natural Fit 8 oz plastic bottle, and there were a few pros and cons about the bottle. The cons outweighed the pros, and we decided to stick with another brand of bottles that would make the transition to breastfeeding easier. Pros: 1. The bottle is ergonomic. 2. It has a wide mouth, making it easy to fill with breast milk or clean. It's also easy to hold. 3. It's light weight. It's easy to assemble and take apart for cleaning. Cons: 1. Both the slow flow angled and straight nipples that came with the 8 oz bottle had a flow that was too fast for my 4 month old baby. As a result, my little one would cough, and spit up the excess milk. 2. After several minutes of sucking on the nipple, the nipple would invert, and baby couldn't suck on it. I would have to keep taking the nipple out from its sucked in/inverted state, so that baby could suck on it again. This was the deal breaker for me, as I couldn't get a full feeding in without having issues with the nipple inverting in the middle of a feeding. 3. It is very difficult to distinguish whether the nipple is slow flow, medium flow, or fast flow. The instruction packet stated that the side of the nipple would be marked with the letter "S" for slow flow to indicate that it was slow flow, but my nipples didn't have any markings with the letter "S." There are numbers on the side of the nipples. The above findings are my observations of the Chico Natural Fit plastic bottle. I received these bottles as a gift from the weeSpring Parent Panel.

I got a chance to try these bottles as part of the weeSpring Parent Panel. We had been using smaller bottles with a basic nipple. I like that these bottles hold more. The smaller nipples we were using would get smashed down when the babies were eating, so I like that this bottle has a wide nipple base, it allows for a more natural latch. My twins are exclusively breastfed and only get bottles when I am away, so it makes for an easy transition. The angled nipple allows for the bottle to be tipped down while keeping the nipple parallel in the baby's mouth.

I got a chance to try these bottles as part of the weeSpring Parent Panel and I was very pleased with them. I have twin 2 month olds and they have been using a preemie flow nipple so I was concerned that this would be too fast for them but they loved this bottle! They didn't spill and didn't drink it too fast either. They didn't really take to the slanted nipple as well.

These bottles are great! There are so many good things to say about them, but I will start with the few cons. There are two things that would improve this bottle for me. The first would be to label the flow on the nipple so when I change sizes it would be easy to tell the difference.The second thing would be to include a travel disc that fits under the nipple so it doesn't leak in transit.There are so many great functions to this bottle. I really love the angled nipple, it makes finding a comfortable position when feeding much easier. My little one gets a much better latch with this nipple than with others we have tried. The material is soft and easy for him to manipulate also. He transitions between this bottle and breast very easily, and has much less burping/spitting up with this bottle. I love this bottle because it is easy to clean and there are very few parts to clean. Their anti-colic valves work better than more complicated systems I have tried in the past. The last thing I like about this bottle is it has a wider mouth so I don't spill a drop of my precious liquid gold when transferring it into the bottle. Thank you to weeSpring parent panel for sending me this bottle to try out and review. Yes, I recommend this product.

I have to supplement with formula and using a bottle, my little one does not like so well. This was a bottle he enjoyed using and it was easy to use. My only complaint is that the nipple sometimes collapses on him while he is sucking and he gets mad as I have to get it back to normal. Thanks to the weeSpring Parent Panel for sending me these bottles!

Great bottle to use with a breast fed baby! Their slow flow nipplee is great, especially for pace feeding. Recommended for moms who want to try introducing a bottle to their little one! This product was provided as part of the WeeSpring panel.

This is my favorite bottle out of the 3 different brands we've tried. The slow flow is perfect for my son and he latches on better than any of the other bottles, including other ones that claim to mimic the breast. The 8 oz size is a little bigger than my four month old needs right now, but it's still very easy to handle. I received this product as a free sample, part of the WeeSpring Parent Panel.
