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.

Over time, milk residues can get trapped in the vent and prevent it from working properly. The best thing to do is to make sure that the ends of the vents (back of the nipple) are clear and free from any blockage. You can easily clean them by kneading the vent tips in warm water. Also, you can sterilize the nipple in boiling water for 5 minutes to clear out anything that may be clogging in the vent.
