Review on Get Natural Feeding For Your Baby With Philips AVENT Baby Bottle Nipples Flow 3, 1M+, 4Pk (SCY963/04) by Jennifer Christensen

If your baby is breastfed and you are trying to make the transition to a bottle, do not read my review, this brand of bottle/nipple might work for you (I cannot say for certain, that is just what I've gathered from other reviews).If you are reading these reviews you have probably gathered by now that there is an "old version" and "new version" of these nipples. If you purchase them from amazon, you will only get the new version. I have read there are select stores where you can still find the old, but it seems they are harder and harder to find.I have a now 2.5 year old son who used this brand of bottle/nipple from the time he was a couple months old (he was never breastfed, we used a smaller bottle for the first couple months). He never had any issues with these and did very well with them.My daughter is now 3 months old. She has also never been breastfed. We used these bottles and nipples for her since she was born, with the "older version" of the nipple that we still had from my son (I know you're not supposed to reuse nipples from kid to kid, shame on me, but they worked). Anyway, she quickly went through the sizes, and a couple weeks ago it seemed the size 3 she was using was already too slow (again, she just turned 3 months old a few days ago). So I went to move on to the size 4 but the only thing I could get was the new version. She would suck and suck and seemingly get nothing out. She would often get exhausted and fall asleep at the bottle. I know it wasn't just that she was not needing the same amount of food because at her normal feeding times she would start to go at the bottle furiously and take in maybe an ounce right away but then she would get so exhausted she would stop or fall asleep and keep "sucking" for 45-60 minutes but barely finish half the bottle. So, I read some reviews and realized the size/flow change that Philips Avent had made. I saw there was a size up (size 5) so I went out to my local store and picked up some of those, thinking it would probably solve the problem. Nope, exact same thing happened. Furious sucking then falling asleep while still "sucking" at the bottle because she was hungry but not getting anything out. The size 5 nipple is supposed to be for 6 months +.my daughter is 3 months old. SO, after a few frustrating days of this on repeat (she also woke up in the middle of the night one night screaming because she was hungry after not eating all day--she hasn't done that in about a month), I decided to make the investment of completely switching bottles. I switched to the Dr. Brown's wide neck bottles (IMPORTANT NOTE: if you already own a set of these philips avent bottles, the Dr. Brown's wide mouth nipples WILL fit into them. The caps don't fit perfectly, but they work, if you want to try to switch just the nipples instead of the whole set of bottles.) I started with the size 2 nipples (which are labeled 3m+) on that set and it was still too slow for her. We went up to size 3 of that brand (which are labeled 6m+) and they work perfectly for her. There are also still 2 sizes up from there, whereas, the Philips size 5 is the fastest flow.Bottomline: if your baby has always been fed by a bottle and not breast or if you are having a baby and don't plan to breastfeed, consider a different set of bottles/nipples.I fully realize that not every baby is the same, and these nipples may work for some formula fed babies (hence two stars and not one), but I think it should be better labeled that these nipples are geared toward babies who are breastfed. And if the time it took me to type out this whole review helps just one parent not have to go through the frustration that I have the last couple weeks, it will be worth it.
