Ay sis, normal lang yan especially pagbago-bago pa lang ang formula! A few of us moms na nag-switch ng milk noticed na mas mabango talaga ang poop muna for the first few days, tapos babalik na after a week or two once their tummy adjusts. Pero kung persistent yung smell at may ibang signs like diarrhea, constipation, o rashes, better check with your pedia para malaman kung okay lang talaga ang adjustment or kung kailangan ng ibang formula, better safe than sorry talaga sa ganito!
