Personally I'm using Avent bottles. I bought 4 bottles to start with and 0+ month teats.
I saw the really small Pigeon bottles before. I dont't think you should use them. Start with bottles that are about 100ml.
I chose Avent because it reduces air sucked in while baby is drinking. It is good to invest in those bottles so that it's easier to burp baby. Too much air in baby will cause stomach pain and they will cry.
Avent bottles are wide necked. For wide neck bottles, babies will put their both entirely over the pointed part of the teat so it mimicks drinking from the breast.
NUK bottles have thoes non-wide-neck teats and bottles. I've never used those types but from what I heard, it's like baby is drinking from the bottle the way they are sucking on a pacifier.
Since you are breast-feeding, I would encourage using a wide-neck teat and bottle.
