The best thing to do is to call your home owners insurance and ask them if they advise putting up signs that say no trespassing and dangerous animal or something to that nature. That way if something does occur the insurance side of it is in line. I personally would put up signs and if a child came on to my property I would call an police officer to escort the child back to their parents with a stern warning. If you try taking them back yourself there's a chance that the parents will freak and say your trying to kidnap them or something. GL
