From experience, or opinion, would you all recommend having different brand baby bottles in case baby just does not like one brand? Or do you just go with the brand you like and/or have used?
I'd buy different just in case. I'm going to be breastfeeding and after a month I plan to pump and start bottle feeding. Baby may not like certain nipples because he's so used to mommy feeding him
It all depends on your personal preference or what you think. I knew before my son arrived that I was going to use Avent brand. That's the only brand I use for bottles and pacifiers. The other kind he doesn't like because he is so used to this. Personally I think if you were to, just use one brand and stick to it.
I recommend that you start with just a few to see how your baby adjusts before spending a bunch of money.
