My baby is 3 days old and hasn't pooped since we left the hospital. he is also having major bouts of gas. he is breast fed?

Breast milk stools: It is not uncommon for breast fed babies to have infrequent stools, sometimes for up to a week. In the absence of abdominal pain, bloating, blood from the rectum or vomiting, this is no cause for concern. Infant glycerin suppositories can be occasionally used if excessive straining or discomfort is present. Rectal sphincter in coordination is commonly confused with constipation.

Other Sx ???: The breast fed baby can have a small smear of poo every feeding or a giant crib filler poo every 7-10 days & be normal. If all of babies stools have been soft to this point & baby is otherwise behaving normally, i wouldn't do much other than wait for the inevitable poo. I baby has dropped his/her feeding activity & changes play patterns, an exam may be indicated. Call the office & check with dr.
