I have 5 snakes right now that will literally come out of their tanks the moment they smell food in the room. My 3000gram cinny will hurl his 5 ft long body 4 ft out of his tank the moment I slid it open. Maybe since you were feeding the two others, your pastel was just hungery and on super feeding mode. Sometimes it just needs to be a wiff on food to make hungry snakes do crazy, never done before things, like bitting the hand that feeds them. I personally don't think you have anything to worry about with your children. Give it like two or three days, and try to get her out and see what her temperment is like. I feel like you will be plesently suprised. Best of luck.
