Ughhh i think my LO one is the pickiest baby in the world when it comes to bottles/nipple. He’s been using mam bottles since day 1. That’s the only bottle he liked. Well I just got a new set of bottles (mam) from Amazon and he rejects them 🙄 they look exactly the same to me. He will not even open his mouth after a few sips and gags.

He hates the blue one. Don’t they look exactly the same ?

Edit: they both have same size nipple. Size 1
