Second Nature Spill Proof Baby Bottles

There are many bottles and nipple manufacturers that claim to be "just like a mother's breast", but after reading about the Flow Control Technology of Second Nature's All-Stages Nipple, I'm starting to think that they may be on to something. These nipples have a flexible membrane of 25 micro holes that flex open towards the baby as a baby sucks. When the baby is not feeding, the holes remain closed to prevent spills and leaks.

The multiple holes resemble the way a mother's breast expresses milk, but it's the Flow Control Technology that makes this particular product unique. Most bottles will let out milk once you turn it over for a feeding and sometimes this can cause choking, but the All-Stage Nipple gives the baby full control of the milk flow. The transition spout, which uses the same technology, allows for a gentler transition from bottle to sippy.
