Hi mama, yes it's actually normal for formula-fed babies to poop less frequently than breastfed babies, a few of us have formula-fed babies din and one of my friends' baby would go 1-2 days without pooping, which stressed her out at first but doctor said it's okay as long as baby looks comfortable and the poop isn't hard like pebbles when it comes. That said, since baby is only 1 month old pa, mas better to check with your pedia just to be sure everything is fine, especially if baby seems fussy or uncomfortable or if the poop looks unusual when it does come. How's baby acting otherwise, comfortable ba?
