Color of poop

Ay, normal yan when nag-switch ng formula, mama! A few of us had the same experience, the dark green to blackish poop usually means ang baby's digestion is adjusting pa lang sa new milk, at less frequent poops din ay okay pa as long as hindi siya uncomfortable or constipated-looking. Basta mombing mo siya for signs na okay lang (wet diapers, aktibo pa rin, walang tummy pain), then I'd say give it 1-2 weeks pa bago mag-settle ang system niya, pero if it lasts longer or worried ka talaga, better to check with your pedia just to make sure lahat's good.
