Ohhh thank you i have no idea no experience at all iam gonna buy one of each NUK and Dr brown and see what she prefers thanks for your answers

Depends on baby but we love Avent Natural.

Breastfed baby but when needed he only accepted the NUK bottles ... I heard the Dr. Brown bottles with the blue/pink straw are good. Bought them & didn't try them. I just gave them away & stayed with Nuk👍🏼
Have a few differnet bottles ready and if your baby has a preference stock up on it 👌🏼🍼dont forget to burp baby or they wake up gassy/spit it all up😭 and have to start again

Every baby is different what pp said buy a couple different.

Evenflo curved bottles

For formula I'm not so sure what to recommend but for a breastfeeding baby I recommend MAM bottles, they are the only ones my daughter will comfortably take, and she gets a nice deep latch as she would with the boob

I have a couple Dr browns and Gerber 0-3 months.. I don't really know either
