@Nicoleta he’s 3 and a half months. He’s had problems with feeding due to CMPA so don’t know if that’s contributed but he just seems to struggle with size 2. I might give him a couple more weeks and try again ☺️
Maybe trying different brands of bottles/teats will help a bit. Dependding how different they are from what you have. But then again, you'd still have to size up at some point. Yeah, just give him a bit more time. After that I'm sure he'd be fine. 😊🤗
How old is your baby? Depending on that could just leave him in size 1 for a bit. My son is 4 months. We started him on MAM size 0, up until 3 months. Then I switched to size 2. Random, I know. But I saw the teats in the store and thought I'd buy them. He's fine with the now.
