My exclusively breastfed baby is 4 months old. He has recently started feeding in a weird way. He suckles and then pulls away(unlatches). Then latches again, suckles and then pulls away. This keeps on happening. I am not sure what is happening. He turned 4 months last week and weighs 16.5lbs. I have never been an overproducer but I do produce enough for my baby. He has been gaining weight as expected. But ever since he started this latch and unlatch breastfeeding technique, its making me doubt my supply. Any idea what’s happening here? PS: This latching-unlatching situation starts towards the end of every nursing session and not during the start.
