I’ve a 3 month old exclusively bottle fed baby and we are using the lansinoh bottles and recently the teats have started to collapse and baby is fussy on the bottle only taking 3 oz compared to 6oz . I have went up a teat size and no help . Also taking 20/40minuts to feed.
would putting the lansinoh teat on the mam anti colic bottles help with air flow and stop tear collapse?
thanks
