Ay normal yan sa 2 weeks old, lalo na if breastfeeding pa lang siya, ang poop ng babies na on breast milk ay usually soft at yellowish, parang mustard, kaya walang problema kahit madalas siya mag-ihi at ang tae niya ay hindi matigas! One of my mum friends' baby din ganyan, she was worried pero the pedia said as long as hindi constipated at hindi diarrhea (like water lang), okay na, at ang baby ay kumakain at tumitigil well. But if worried ka talaga or if makikita mo na may blood o something unusual, best pa rin mag-check sa doctor para ma-ease your mind, momsh.
