I have tried them all (almost). Why, you ask? Well, since Mason has been eating formula, he has been using the small wideneck BornFree bottles. The only problem was that they only hold 6 ounces and he was starting to eat more. Plus, he never had any stomach problems and I didn't see the point in continuing to clean a bottle, nipple, ring, cap, and two parts of a vent. So the hunt for new bottles began. I started buying what I thought looked like the best bottle but always found a problem and had to return and exchange, moving onto the next one. Here are my reviews* of the bottles I have tried (all are BPA-free):
BornFree: A-. Great bottles. Lots of parts. Highly recommend to use the 6oz widenecks as starter bottles so that you are covered in case you have a spitter.
Playtex Drop-Ins: B. Also great bottles. The only downfall is having to purchase the liners for them. Good for "lazy moms". I used these in the beginning along with the BornFree's.
MAM: D. The only reason I didn't fail these bottles is because they are cute. That's it. Thought I was getting less parts to clean. WRONG. The bottom screws off to reveal a vent system. They leak. They suck.
Avent: C. Good bottles, but leak horribly. Unless you have tons of time and patience to stand at your sink, dripping with formula, trying to screw the top on just right, don't buy these bottles. Plus, they lagged a little in the BPA switch-over. Losers.
Nuby: B. Adorable bottles, and MY favorite. No leaking issues BUT Mason didn't like them and I guess he gets a say. The "vari-flow" nipple was too hard for him to grasp since I guess he is lazy sucker. He did like to chew on the nipple though since it has little "nubs" that massage gums.
Gerber: A. Old school $3.99 for a 3-pack bottles that your mom probably fed you with. Good bottles, latex nipples (not my favorite, I prefer silicone but Gerber doesn't offer silicone until the level 3 nipples) BUT I found that the Evenflo nipples fit just fine.
Evenflo Pure Comfort (or something): A. This is what I am using now. So far no issues and I love that the bottle is angled for comfort. Little to clean, cute colors, no leaking. I think these are a keeper.
*I am not getting paid or anything to do this, just thought it might be helpful. Cheerio!
