My 6 day old newborn has not had a bowel movement in almost 2 days. Should I be worried? She is strictly breastfed.
Strictly breastfed babies may have from 10 diapers with stool a day, to one diaper with stool every seven to ten days. Breast milk can be so perfectly suited to the newborn that the newborn is able to absorb absolutely everything in the milk, and the only waste is liquid :)
The important thing is that the newborn is urinating frequently, and has many wet diapers every day.
Also, newborns that poop seldom may be uneasy up to a few days before pooping.
Additionally, if the newborn is fed formula milk, there should be a diaper with stool every day.
