Ok, So my DS1 (2yrs old) is ALWAYS playing with himself. He will do it all the time anywhere, ever since he got potty trained just before christmas. He will get himself hard and the cry because "doodle's ouchy mummy".

I know this isn't abnormal as such but have very little experience with boys and was wondering how I should be handling it. At the moment I just keep on telling him to stop playing with it, or it will hurt.
