Baby drinking lesser

Ftm here too.. jiayou! I’m also trying to find the right amount to feed baby… every baby is different, for me, my baby Juz hit 1 month.. he can take 70ml max 100ml but when he takes 100 ml… he cannot go to sleep immediately cause he will vomit milk out. We feed on demand - when he is hungry he will cry… I guess it will help if you sit him up right for at least 30 mins after feeding if he is drinking more than his usual to prevent him from vomiting or spitting…

All babies are different. Even so, their intake will also change from time to time. Whatever amount he takes in, as long as the diaper output is good I wouldn’t worry too much. Don’t force feed as it might backfire. If baby is throwing up after milk, it might be too much for him to take in.
