Poop interval

Ay, four days is medyo matagal na talaga, lalo na kung hindi sya ganyan dati! Usually when babies switch formulas, especially sa mas matinding NAN like Infinipro, it can take a few days para mag-adjust ang digestive system nila kaya constipation is not super unusual, a few of us switched formulas din at similar experience namin, pero if it's been four days at wala pa rin or kung uncomfortable sya, it's best to check with your pedia na lang para sure. In the meantime, try warm water in between feeds if okay lang sa doctor, sometimes it helps jumpstart things. Did baby's poop pattern before the switch ay regular ba?
