ARGH I wish this thread had been going about a month ago.
DS2 has an epithelial pearl under his foreskin and the GP said that he was shocked that we hadn't been pulling it back to clean it - he said it was vital that we do it and vital that we do it with DS1 (6) to avoid circumcision.
so when we got to the hospital about his willy the urology consultant said what all the ladies above have said Don't do anything with it but once they do come back make sure your child knows how to make sure it is really cleean.
Update apointment with different GP who said to remember how vital it was to pull the foreskin back to clean it.!!
I told him what the hospital had said and he admitted that it is totally dependant upon the culture you were bought up in and there isn't a medical right time for the foreskin to retract.
