Do not pull it back. It can cause scar tissue to develop, attaching the foreskin to the gland. Which will then cause a medical reason to circumcise at an older age
. It will naturally release as he grows older.
That makes SO much sense to me, I believe that is what happened to my son. He was not circumcised and I cleaned him in the manner I was taught, not to pull the foreskin back. When he was about 3 months old, I was cleaning him and his foreskin just popped back! Scared me to death. He did develop what I now believe were adhesions and had frequent episodes of painful swelling and infection of his foreskin. He had to be circumcised when he was FIVE. It was one of the most traumatic experiences of his, and my, life! The doc told us he would quickly heal. For TWO WEEKS he stayed home from school in so much pain. A scab would form on his meatus and would have to come off when he peed, and he would just bleed and scream. It got so we had to put him in the tub every time he had to pee.
To the OP, if you were talking about your son when you said your friend pulled the foreskin back, just keep good watch over it. I am not really pro-circumcision, but I always said if I had another son I would have him circumcised immediately due to that awful experience. Who knows what scars THAT experience left on my son? If your son's foreskin is still intact, just make sure to keep it so until it retracts naturally.
Good luck! Aren't little boys great??
