I have a seven year old boy who came to me the other day and asked me to make him a doctors appt because  for the last few days "his pee-pee has been getting hard and he's been trying to make it go away but it feels like there is a bone in it". I am certain that he is not starting puberty. However how do i explain to him (seven years old) that this is a stage that boys go through. And that we don't need medical attention
