Dear doctor,
I have a 3 1/2 year old son. within the last 3 months, the hair on his arms and legs seems to be growing in darker and rather rapidly. I do not know how to guage "normal" hair growth in a child of this age, so my question is - how do I know if this is excessive or normal? It seems like he has more hair and it is darker then most children I've seen his age. Also, he sometimes get's really sweaty palms...just sitting still watchin TV or doing anything where he is not actually using his hands. The hair on his head seems to grow at a normal rate, he is of average size and weight...and is perfectly healthy according to the pediatrician. One other thing, I have also noticed that when he gets an erection (mostly in the morning after waking up) the skin just under the head of his penis seems more red then normal. He is circumsized. He does not show any signs of pubic hair, or abnormal facial hair, or hair anywhere else on his body. I want to be clear though...we're not talking gorilla hair here, but it just seemed to come in rather quickly and darker then what I expected. Do I need to be concerned about this??? Any help you can give would be greatly appreciated...thanks.
