My son is 3.5 yrs old and never had any REAL problems...
The only problems we've ever had were doctors... like the doc who insisted my sons high fever MUST be due to a UTI, you know, because he is intact... he was wrong, it was viral. And the urologist who insisted that we need to use steroid creams on ds to help rid him of a smegma pearl, threatening circ if we don't follow her advice
: WRONG! (Pearls are a normal part of the separation process for some boys, in case anyone reading this doesn't know... they are not a problem, and should definitely be left alone!)
Really, thank goodness for this board and NoCirc, I've saved my son from unnec caths and steroid creams and who knows what else!
