Aw mama, kaya mo yan, colic at 4 months is so rough, and it's totally normal na babawasan ang intake niya during this phase kasi uncomfortable siya A few of my mum friends had colicky babies too, and they said parang around this age talaga ang babies get fussier with feeding dahil sa digestive discomfort, kahit kumakain pa rin at tumatagal ang weight gain, pero definitely bring this up sa pedia on the 26th, especially kung nakita mo na dramatic change sa appetite niya, kasi puwede ring may iba pang factors na kailangan i-check. Just document kung ano ang pattern ng feeding niya and kung anong time siya mas comfortable, para ma-share mo sa doctor ng malinaw, they might recommend adjusting formula, checking for reflux, or other things na tutulong sa colic niya para makakain siya ng mas okay ulit
