When my child was circumcised I apply engine oil the natural one and the penis dry b4 1 week

Hold him carefully so you don’t put pressure on his penis. The tip may be sore, and the penis itself may look red and swollen. You may see a yellow crust on the tip as well. This is normal and should go away on its own in a few days. It will take a week to 10 days for your son’s penis to heal completely.

It’s fine to wash his penis as it heals. You should change his bandage with each diaper change, applying a dab of petroleum jelly first so it doesn’t stick to his diaper. Around 48 hours after the procedure, the bandage is usually not put back on once it comes off. Lubricant, though, should still be used to keep the penis from sticking to the diaper. If stool gets on his penis, gently wipe it away with warm, soapy water. To ward off infection, change his diaper often and fasten it loosely.

​Leave your infant's dressing on for 24 hours after the circumcision.
While your child is healing, apply a petroleum-based ointment (such as Vaseline) to the end of the penis after every bath and with each diaper change.
Go to the nearest emergency department if your child has excessive bleeding, fever, worsening redness or swelling, yellow liquid draining from the incision or difficulty with urinating.
