Moving from nursing to bottle can be difficult. Made to mimic natural breastfeeding, the Comotomo Baby Bottle is a skin-like, soft and squeezable body with a naturally shaped, soft, silicone nipple intended to ease the move to bottle feeding. Babies that have trouble moving from breast feeding to bottle have a more familiar feeling. It also helps moms who would like to go back and forth between breastfeeding and bottle. Minimal parts and an ultra-wide opening allows for easy cleaning by hand. Built-in vents are designed to prevent colic, while helping to completely eliminate leaks. Bottles and nipples are made with medical grade silicone that are heat-resistant to provide a safe bottle-feeding solution. *8oz bottles come with medium flow nipples (2 hole) designed for 3-6 month old babies.
