Newborn babies should urinate several times a day. Stooling patterns vary widely from after each feed to every four to five days. Babies’ stools are often mistaken for diarrhea because they are very liquid and usually yellow and seedy. Straining is common and is not a sign of constipation. Hard stool or pellets are signs of constipation. Feel free to call for advice about constipation during regular office hours. Do not give your baby an enema unless instructed to do so by a nurse or doctor.
