my baby has not done 💩 from Thursday she is only 15 days old

A. hello...happens to most babies....nothing to worry about until baby is happy and active and feeding...Infants older than eight weeks often go 4 or 5 days without a dirty diaper/poop, and it doesn't mean they are constipated... breastfed babies, especially if they have not started solid foods, can easily go two weeks without a poopy diaper once they are 2-3 months old...
