Newborn is 4 days old and there is foul odor coming from umbilical cord stump but no discharge. is this normal?

Keep close watch...: Keep area dry. During the healing process, it's normal to see a little crust or dried blood near the stump. Contact your baby's doctor if your baby develops a fever or if the umbilical area: appears red and swollen around the cord, continues to bleed, or oozes yellowish pus or has foul-smelling discharge. Smelly alone is ok, but watch closely.

Abnormal: Foul smelling umbilical cord stump indicate bacterial growth-which is not good. This may be treated with alcohol swabbing of the stump several times a day. If it drains fluid or remains foul smelling, or the area around it turns red-a visit to the doctor is recommended. You want to avoid omphalitis.
