Give your baby a warm bath soak. 20 minutes or more. Keep putting in warm water to keep it warm.
Then use massage oil, unscented. Baby oil is fine. (Silicon sexual lubricant is better. I sell it on my webpage
http://www. sexsupport.org/toys.html - I think it is so great.) Massage his penis and gently push the skin back. If you can get your finger inside the opening of the foreskin -push your finger in and try moving you finger in an expanding circle. You can do this 3 times a day.
PLEASE don't feel any guilt for doing this. You are doing this to help your baby - there is nothing sexual about it.
If they talk about a furth er circumcision they might be thinking of a dorsal cut - where they cut a bit lengthewise
Good luck and let me know if you have any success - it might take a week or more.
