honestly i think itd be worth getting new bottles. nipples i feel like are so expensive in themselves, so might as well get new bottles to go with them. idk if that makes sense, but then you could pick out some new colors too! i use mam bottles too, i love them
@Jaylean that's kind of what I was thinking too! Both my boys loved the mam bottles!
Ehhh if they have already been reused then I’d say yeah probably replace because of degrading and what not. But other than that replacing nipples could be good
