@monicaaa just keep giving her formula and let her body get used to it and work it out. Worst case scenario, talk to her doctor about it if it persists and see if a formula change is needed. I had my son on Enfamil Infant but now he's on Enfamil Gentlease and he's back to having 4+ poopy diapers a day
Are you formula feeding? You may have to change the formula if you are but otherwise, just keep feeding her and eventually her body will work it out. Mine was constipated at 1w and the doctor told me to switch his formula and continue feeding him because he'll need the fluids
