The Olababy GentleBottle is the natural solution to dated bottle designs. This bottle helps children who are dealing with colic and also those who have difficulty latching. The mouthpiece was designed to mimic the breast, so that baby will have a recognizable shape to latch on to. The bottle is made of 100% BPA, PVC, and Phthalate-free silicone, which makes it safer than glass bottles and much easier to clean. Three color designs were chosen to make it as visually appealing as it is effective. The off-centered nipple makes it easier to get all of the liquid out when feeding. It is truly designed with baby and parent in mind.
