Baby reject milk 5 half mth

My baby also reject milk for a period of time during 5-6months old. I wasn’t sure why but he was not injured, poop looks okay, not extra sleepy and still having fun so I just sort of like monitoring him only. But this only lasted a few days and he went back to drinking as per usual. Did yours just started?

I'm also facing this issue 😐 my baby is 4m+ supposedly be drinking 180 ml in 4-5hr but instead she's still at 120 ml every 4hr . she's not fussy at all . been having 2-3 nap during the day . when at night she then starts to drink more milk 😐😐
