A newborn's bowel movement frequency can vary widely, but here are the key points about how long a newborn can go without pooping:
- In the first weeks, many newborns poop 1 to 5 times per day, sometimes after every feeding. This frequency often decreases over the first month as the baby matures
- By about 6 weeks of age, it is common for babies to poop less frequently, sometimes only once every few days or even once a week, especially breastfed babies. This is because breast milk is very efficiently digested, leaving less waste
- Breastfed babies can normally go several days without a bowel movement, sometimes up to a week, without it being a problem as long as the baby is feeding well, gaining weight, and seems comfortable
- Formula-fed babies tend to poop more regularly, often daily or every couple of days, but some may go up to 3-4 days without pooping
- Going more than a week without a bowel movement in a newborn is a reason to seek medical advice, regardless of feeding method
- It is important that stools remain soft; hard, pellet-like stools or signs of discomfort could indicate constipation and should be evaluated by a pediatrician
In summary, a newborn can typically go up to about 5 to 7 days without pooping, especially if breastfed, as long as they are otherwise healthy and comfortable. If a newborn goes longer than a week without a bowel movement or shows signs of distress, medical attention should be sought.
