My 18 mo. old son suddenly developed a protruding belly button. he is as active as normal and shows no sign of being bothered by it, even when i poke around it.  It looks as if he has a serious "outtie" belly button but i assure he does not and never has.  i am worried his doctor is closed forthe day... what should i do?
Hi, It seems that he might be developing umbilical hernia giving rise protrusion of belly button. Nothing to worry, with having strong abdominal muscles it will be alright. Consult your doctor, he might put a coin over the part with covering adhesive tap and will keep for some time. This procedure might cure his problem. Avoid constipation or cough reflex. Ok and take care.
