Q: How do I care for my baby's circumcised penis?

A: It's OK to wash the penis as it's healing. Change the bandage with each diaper change, and apply a dab of petroleum jelly to the tip of the penis to keep it from sticking to the diaper. If there's a plastic ring instead of a bandage, it will drop off on its own — usually within a week.

Problems after circumcision are rare, however you should call your baby's doctor if:

1. Your baby doesn't urinate normally within six to eight hours after the circumcision.
2. There's persistent bleeding or redness around the tip of the penis.
3. The tip of the penis is swollen.
4. You suspect an infection — there's foul-smelling drainage from the tip of the penis, or crusted sores fill with fluid.
