Baby poop normal

Hi mommies, question ko lang normal Lang bang di nag poop si baby ng 4 days? Mixed feed sya (breastmilk plus milk na s26), and 1 month old. panay panay lang sya ire, pero wala naman lumalabas. Nagwiwiwi sya lagi at utot. Kaso poops nya lagi g 3 to 4 days bago magpoop#firstbaby #advicepls
