I used this booster (different color) for my first-born til he was able to sit on his own at the table. I now use this for my second-born who has special needs. I have even ordered extras to leave in the car & for grandma's! My 4 year old is unable to sit still & stay seated without being strapped in. This is the only booster that we can still strap her in & she still has room to grow!! She's too big for a restaurant high chair & restaurant boosters don't have straps. Eating out can wear us out... this booster seat is an ideal solution for us!! We LOVE it!!
