#AskTheExpert my baby has not pooped for 2 days , however, he is passing wind once in a while. How long should I wait before I visit a doctor?

A. Call your baby's pediatrician immediately if your newborn baby (under 6 weeks old) is not pooping at all. Also call if your baby (of any age) has constipation for longer than 5 to 7 days or if they also have other symptoms.Call your pediatrician if your baby hasn't pooped for more than three days in a row. Formula-fed babies typically go a little longer between bowel movements. Check in with the doctor if she doesn't poop for more than five days as that could be a sign of constipation.
