What to expect with toddler circumcision healing time?

He shouldn't need to be circumcised. If he had been circumcised at birth then the bee would have stung him on the shaft of the penis, and that would have been even worse. Leave him intact and the swelling will go down with time, then the foreskin can continue doing one of its most important jobs- protecting the rest of the penis, just like it did in this situation.
