I want to register for bottles and corresponding breast pump accessories, but my first problem is that I have to find out which breast pump my insurance covers and secondly, what if he doesn't like the bottles I pick out! Should I get 1 or 2 of several brands to see which he will take? I'm hesitant to register for those bottle kits with all those accessories and warmers, etc if he for some reason won't use them. What do you think? Thanks!
