Umbilical Cord & Navel
The umbilical cord is nothing more than a remnant of unnecessary flesh that has no nerve or blood supply. Your baby can not feel you touch the cord, and of course, it does not hurt him/her to do so.
The cord usually falls off in about a week, but some babies may keep theirs closer to a month. To promote drying and lessen the chance of infection, the cord should never be covered by bands and you should try to keep the diaper folded out and down below the navel.
