Glad you and the boy both came out ok. Shooting some one is the last thing anyone wants to do. The only thing I would recommend is having a very bright flashlight. Any of the current tactical type lights would do. I have a Surefire 6P that I just fitted with a 120 lumen CREE LED light and it lights up the area very well. At 20 - 30 ft the other person will be nearly blinded for quite a while. Nothing like shedding a little light on the target before making the decision to shoot.
