We registered last night and I think we did ok, but I was so overwhelmed at all the different bottle options! I've heard to register for several different kinds (because baby may not like certain types) but I have no idea where to start! Glass or plastic? 4oz or 8oz? Brand? Nipple type? Bottles for colic? So confusing! What did you register for (and like)?

Also, bonus question. I want to get a bottle warmer, but am unsure if other brands will fit in a certain brands warmer? For example, if I get Dr. Browns and munchkin bottles but have a munchkin warmer - will the Dr.Browns fit?
