Every parent will experience one; most children will have one. When you see a child having a melt down, he/she is probably tired, sick or hungry - or the parent is not allowing the child to get his/her way. That child's parent/s want to get out of that store just as bad as the youngster, so allow the family to go ahead of you at the check out. And don't say, " You sure have your hands full!" You might get slapped.
