We are currently using the MAM size 2 teats and we have a 6 month old . I feel like the size 2 are getting too slow for her as she seems bored after a while into the bottle and starts chewing the teat and not finishing bottles etc , we have tried the size 3s but they are just way too fast they just pour out , has anyone got any recommendations for a teat that is inbetween MAM teats 2 and 3 that fit on MAM bottles? Thanks x
