Oo normal lang yan, mama! One of my mum friends was also surprised ng baby smell ng poop ng second baby niya, parang talaga namang matapang compared sa firstborn, pero it's just how their digestive system develops differently or sometimes it's what you're eating na reflected sa breastmilk niya. As long as baby is gaining weight, happy, at normal ang diaper output niya, walang alalahanin!
