Philips Avent Newborn BPA-Free Nipple - 2 pack

The Avent Variable Flow Nipples allow formula mixed with cereal to pass through the nipple hole with ease. At a baby's young age, when the flow must still be relatively slow, you can turn the nipple so the Number I that's embossed in the nipple is lined up with the baby's mouth. This allows the formula mixed with cereal to still pass through the nipple hole easily, but doesn't cause the baby to choke due to the formula flowing too quickly. As your baby gets older, you can turn the nipple in his mouth so the Number II is lined up with the baby's mouth and this allows for a quicker flow, and, ultimately to the Number III "setting". The only two negative things I can say about these nipples is that (1) you can't find them in any store. After finding the initial two packs of nipples in a popular baby store, I had to buy the next two packs over the Internet. They weren't available in any store. And (2), there are no instructions with the nipples to explain how the variable flow works and how the numbers correlate with the rate of the flow.

When my daughter was born I planned to strictly breastfeed her for the first month at least. However, complications from jaundice forced us to introduce the bottle on her 5th day of life. The Avent system with the Newborn Nipple allowed us to provide her with both expressed breast milk and formula supplements with ease. Since then I've tried other bottles & nipples. Nothing compares to the gentle flow of the Avent Nipple which feeds her at just the right pace to avoid gas and spitting up later. We now use nothing but!

These are the same as the one hole nipples that come with every new Avent bottle. I went back to work only 6 weeks after the birth of my daughter and I believe the unique shape and anti collapse design of this nipple kept her from becoming confused and preferring a bottle. For moms who nurse, I would not recommend more than the two hole slow flow nipples, even with an older baby. The slow flow rate makes them realize that the faster easier way to get milk is from natures source, your breast! Even with the one hole flow rate, my daughter finishes off a bottle in 10 minutes flat, I don't worry that she needs a faster flow.
