The world continues to change right before our eyes. But why is it that baby bottles are the same old unflattering tools? After all, isn't the baby bottle one of the first objects that your baby experiences through all five senses? Why should mothers have to worry about toxic plastic & colic-inducing design for something so basic & important? We found no good reason & decided to challenge the status quo. In our voyage, we've learned an important lesson. Inspiring products are born only when we think with a mother's heart & experience through a baby's eyes. We proudly introduce ComotomoTM Replacement Nipples. Comotomo Nipple Packs are replacements specifically designed for Comotomo Baby Bottles. Each pack comes with 2 silicone nipples designed to most closely mimic natural breastfeeding. Our naturally shaped, soft, silicone nipples are ideal for babies who have trouble transitioning from nursing to bottle feeding. Each replacement nipple also has two truly innovative vents that are built in to prevent colic, while totally eliminating leaking issues. ComotomoTM Replacement Nipples grow with your baby, and are available separately in 4 stages: truly Slow Flow (1 Hole) for ages birth-3 months, Medium Flow (2 Hole) for ages 3-6 months, Fast Flow (3 Hole) for ages 6+ months, and Variable Flow (Y-Cut) for ages 6+ months (thicker fluids).
