The GentleBottle is made of soft medical grade silicone that is 100% toxin free. The soft texture and shape allows baby and parents a safe and comfortable grip. The off-set nipple design mimics a natural breast that allows for easy latching and reduces bottle rejection. The attractive colors of our Gentlebottle helps to stimulate baby’s visual senses, allowing for a strong role of direct experience with colors in the early stages of visual development.
