Ay normal lang yan, mama! At 3 months, ang babies especially kung breastfed ay madalas talaga mag-poop 3-4 times a day, some of my mum friends' babies pa nag-poop after every feed, so you're actually on the lighter side, haha. As long as soft ang consistency (like mustard or cottage cheese) at hindi constipated o may blood, okay na yan at sign na kumakain siya well. But if worried ka talaga or may changes sa color or consistency, better check with your pedia just to be sure!
