Momsh, at 3 months on formula, normal baby poop can actually vary, meron kasing yellow, tan, or brownish shade depending sa formula brand, at pwedeng once a day to a few times a day, so hindi lang one answer! But para sure na okay lang talaga at walang concerns like constipation or loose stools, mas better if you check with your pedia, they know your baby's feeding pattern na at makikita nila agad if something's off, kaya go lang sa check-up para peace of mind mo!
