Ang kulay at consistency ng poop ay usually magbabago talaga when you switch formulas, kaya normal lang yan! A few of us mums tried switching from Nestogen to Lactum, and lahat ng babies namin had different poop for a few days, some mas maaring, some mas solid, depending sa baby. Basta wag mo stress if iba na lang ang dating for the first week or two habang nag-adjust ang tummy niya, pero kung may mucus, blood, or very watery poop na tuluy-tuloy, better check with your pedia just to be safe ha.
