Ah, yan ang meconium or ang early poop ng newborn, it's normal, lalo na sa first few days! Ang yellow-greenish at sticky na tae ay sign na kumakain na siya ng colostrum, which is really good. Pero kung persistent ang yellow at parang mucus-y or may blood, or kung concerned ka talaga sa color at consistency, mas maganda i-check with your pedia just to be safe, bawat baby ay different kasi, at mas mapapanatag ka lang.
