There is no standard amount on how much a baby should drink. My friend’s baby drinks 160ml~200ml while mine only drinks 80~100ml (3-9mo). Despite that, she’s also gaining weight steadily (sttn too). At 10mo, she’s drinking 125ml, at 14mo 210ml, 15mo 180ml.
Dont force feed, it may backfire.. If your LO’s diapers output is good, pale pee (no dehydration) then I wouldn’t worry about it. 😊
