Should i be concerned about a herniated belly button?

Benefits fetus: It helps a fetus to have loose belly muscles.Otherwise the blood passing into the belly button from the placenta would have a hard time at that tight area.After birth, the strap muscles of the belly remain loose until baby begins to sit up, pull up & otherwise tighten them.At that point, most pooched out bb's go back in.If still out after walking a year, i'll have them evaluated for surgery.
