Help pls! Our five month old baby is bottle fed expressed breast milk and Aptamil formula from birth. Haven't had too many issues with feeding until now. Literally today. His mouth moves a lot, and he fusses and cries in a manner that usually indicates that he's hungry. But he's repeatedly rejecting the bottle when offered. I tried switching between slow flow teat and medium flow, no luck. Tried different feedings positions. Now my partner has come back from work he's also trying with no luck either so far. Baby usually feeds 800ml-1000ml every day but today he's done only 500ml so far.
Baby is drooling a lot today, and his left cheek is visibly redder than the other. Could it be teething? If so how do you get a teething baby to feed? Thanks!
