Obviously I'm not a BTDT mom, but I did some research for when we registered.
I haven't read the PP responses, so this may be duplicating some great advice I am sure you've already received.
I have an Avent pump and Avent bottles from when I BF and pumped for the first 12 mos for my little one. And I plan on using them for Baby #2 (after I conceive)
Here's a quick rundown of why I like(d) them.
Avent let's you pump directly into the bottle.Storage caps/discs, so you can just screw on the nipple.Everything is interchangeable.They are the safe plastic of course.They stood up to sterilization and dishwasher cycles.They come in a variety of sizes (4, 6, 8, 9 and 11 oz)Marked in metric and us measurements.
I gave my bottles away to a co-worker who was fostering a baby,she kept the baby for 1 week and still has my bottles! So I'll be using all new bottles. Not that I'd want the bottles back, but I gave her a bathtub, clothes, toys, etc thinking she would have the baby for a couple of months. But I digress...
I used the Advent bottle/cup system w/ DS. He had a bottle introduced around day 2... I had supply problems and he was tongue tied. Eventually we got the BFing down, but I did have to go back to work at 7 weeks PP... so it was really helpful to already have him used to bottles as well. I like the Advent because they have the nipples w/ the different flows for different ages/stages.
However, their manual breast pump sucked (at least 6 years ago).
I agree with the PPs that every baby is different and you may have to try a few different bottles. We are still working on getting Selin to take a bottle. The first two times she absolutely refused and the third time, I actually waited in our garage while DH fed her and she took the bottle that time. I got that suggestion from my La Leche League group. They also told me to try having DH give her the bottle when it's not necessarily feeding time so she wouldn't be ravenously hungry. I also plan to have my mom try giving her a bottle sometime soon so when I do go back to work in a few months, she will be used to having others give her a bottle.
So far we've only tried the bottle that came with my Medela pump. I have heard good things about Dr. Brown's as well.
This is such a tricky decision because every baby is different! I think you'll just have to try one out to see if your little one likes it... and if not, then just start trying other brands!
Here's our experience... we started with the Avent bottles, she didn't like them and thus wouldn't take a bottle very well at first. Then we tried the Nuk nipple, then we tried the Dr. Brown's bottle...you get the picture! She HATED all bottles/nipples. Then recently we bought a Breast Flow bottle, and she seems to prefer that one. It is the most similar to the breast, I think - the base of the nipple is VERY wide and "requires both compression and suction" (as the company says!) - well, Eliza must like that because it is the only bottle she'll even think about taking.
I hated making this decision when I was registering! You can't really go wrong, just start with one and try it out, maybe she'll like the first one you try, you never know!
We've liked the Avent bottles with the wide mouth. Not that he's tried anything else, but we started bottles at 10 days and have never had any trouble going back and forth.
