Ds nearly 4mo. Mix fed. Realised today he is only getting about 500ml ff a day and the rest is bf which is a bit in the day but mostly after first wake up around 2am from when we co-sleep/feed all night. Realised today given he is big and around 8kg he needs between 1200-1600ml per day (based on baby centre saying 150-200ml per kg) he really needs more food in the day to break the waking and feeding thoughtful the night thing. Any tips on how to do this though? Just gave bf and then bottle and though obv I don't know how much bf he got he only took 30ml ff before pushing it away.
