Foreskin still attached to glans on 7-year old

I was wondering if anyone know of any homeopathic remedy that would help in the following case:

My 7-year old son's foreskin is still largely attached to the glans, and I know that there is no particular rush yet, to get it to retract completely, but there is a small problem of the foreskin having loosened itself in some areas, which then create almost closed pockets, which are not easy to clean, since he can't get the foreskin all the way down everywhere.

I have told my son to try to pull the foreskin down reasonably hard every time he has a bath, which moves the foreskin back a tiny bit, but I just wondered if there is a remedy that can help speed up the process to get the skin mature enough, or whatever it is that needs to happen, for it to detach itself.

Many thanks in advance,
Susanna
