Ay, normal naman yan sa 3-month-old, lalo na kung exclusively breastfed, maraming babies na ganyan lang, once a day poop or even less frequently. Pero since tatlo na ang beses na may greenish/mucousy or unusual stool, mas better magpa-check ka sa pedia para ma-rule out ang possible irritation or milk sensitivity, kasi baka lang kailangan ng adjustment sa feeding or formula if gumagamit ka, yun lang para ma-peace of mind mo at ma-ensure talaga na okay lang si baby.
