Your first response would be to put your child in the car and shut the door.  Not pull a weapon..in front of your three year old child.  Again I will ask...did anyone see his FB sight before he took it down?  I was even more concerned after I saw the picture of what I will assume were two of his children in a bathroom stall.  It is one thing to take the picture...another to post it on an open forum.  If indeed these are his children on his page...in my estimation?  He makes poor choices.
