some of my friends' baby boys did the circumcision the next day after they were born. i heard that it's very easy surgery for the newborn. the doctor just put something (topical) on the bb's penis and cut the tip off.
they said the babies usually get fussy for the next couple days but they'll recover in abt a week. and they said the babies will suffer less if they have the circumcision as a newborn compared to an older age.
however, we didn't do it for our boy coz my mother-in-law (who worked for a public hospital in HK) said it's still a easy surgery in case he might need it at 4 to 6 yrs old. and she said it's cheap to do it in HK.
