If your infant son has been circumcised, the tip of the penis may appear swollen
and red for a few days afterward.
You should wash the area with a soft wash cloth and apply a thin layer of A&D ointment to the tip during diaper changes for the first 3-4 days. Do not be alarmed to see a yellowish tissue forming on the surface of the tip of the penis as it heals.
This is part of the normal healing process.
If your son is not circumcised, no special care is needed other than normal cleansing. You will need to pull back the foreskin with each diaper change and bath to be sure to get any stool or dirt off the head of the penis and the skin folds.
For girls, it is normal to see a small amount of blood appear in the vagina or on the diaper during the first few days. This is called false menstruation, caused by a normal shift in hormones after birth.
