We love Dr.Brown products

We were totally unfamiliar with baby bottles and the things that go with them before this past summer- after a lot of trial and error with different brands we've become huge Dr.Brown fans!! These bottle nipples in particular are awesome and it's been pretty obvious (in my opinion) when baby is ready to move to the next size and it's actually lined up pretty perfectly with the intended ages per size for this product!

great!

level 1 is too slow for my 7 week old twins now, so i got level 2 and it is perfect! I like the Dr Browns bottles, but they leak a lot, so I just get the replacement nipples and use them on all other standard size bottles and they work great! they do collapse easy though.

I'm very satisfied with Dr. Brown's Natural Flow Preemie Flow ****! They're perfect for my little one, providing the slowest flow as needed. The quality of the silicone is excellent, and they fit the bottles perfectly. Highly recommend for newborns and breastfeeding babies! Five stars!
