It is normal for snakes to always be hiding, especially if they are young. Corn snakes are primarily nocturnal anyway, so they come out at night. The reason he darts away is because he is young and scared. Just keep handling him for about 10 minutes a day and he will calm down.
My son and I are sharing the hobby also. He was afraid of snakes (I can't imagine why, he certainly didn't get that from me) until just a few months ago. Now he shares almost every aspect of their keeping with me. He is still a bit squeamish about feeding though. He says he can't bear to watch that little mousy face going into the snake's mouth. I explain to him that the mice are already dead and don't know what is happening to them, and he says, "Yeah, I know, but still I just feel so sorry for the mouse!"
I guess that means when he grows up and goes off on his own, I'LL get his snakes! :grin01:
