My little boy has the nuk ones, they are flat on the bottom. He's taken to them really well. He has tommee tippee teats when he occasionally has a bottle, but is pretty much EBF. But every baby is different. There is a set on amazon that you can buy that has a few different shapes of teat. Not sure if that's worth a try? Xx
Not related to chubby cheeks as such (my daughter does have some chubby cheeks) but hasn’t got on with mam ones at all and had only successfully taken to tommee tippee dummies even though her bottles are mam xx
We were using Mam 0+ dummies and the same seemed to be happening with our LG. When I looked in the supermarkets & big Boots etc I could only find 6m+ ones but then randomly in a small Boots they had some 2-6m Mam ones, so I bought them she seems to be doing better - she still pulls them out but that’s just a game 🙄😅 The teat (is that what it’s called?) on them is the same size as the 0+ ones but the back is bigger, if that makes sense. I looked at the 6m+ ones but the teat on them looked a lot bigger x
