At first I saw funny and natural side of my son being curious about his body, but now I feel concerned about him playing with his penis (so much). Is this normal? He seems to find every opportunity, at the dinner table, whilst playing with toys, when we were on a bus yesterday! I'm worried he will hurt himself, I'm also worried about the constant and frequent element of this. Note, he has DLD (a speech and language difficulty). I do try to do sensible thing and explain to him about this being a private thing. But now resorted to telling him it will fall off if he plays too much with it to try have an impact on him to stop but it's not working. What should I do? And am I right to be concerned?
