I don’t understand my LO is 11 weeks old today (formula fed), my issue is that until 6 weeks old he drank around 4 to 6oz per feeding every 4hours (30-32 oz per day). But since then, he drink way less, like he only drink 2.5oz per feed and even less sometimes (20-22 oz per day) and i don’t know what to do anymore, if we try to feed him more he screams, but during his nights feed he will sometimes drink 5oz bottle. I don’t know what is going on with him, I am starting to get worried that he is not getting enough, and why did the quantity of milk drunk dropped?? We think it might be silent reflux but why was he ok like 3 weeks ago? I am at my wits end

Info: he is 12lbs, and does enough wet diapers, i am not worried about desydratation

Hi. I need help, my 8 weeks old suddenly won’t sleep his usual 3-4 hours nap during the day that he used to do and he (formula fed) used to drink 140-180ml(6oz). But now he only drink 60-80ml(2-3oz) and sometimes he still drink 160ml. I don’t know what to do he seems normal and still a “happy” baby.
