Any parent will tell you the frustration you feel when your child throws a tantrum. For some reason, they will always pick the most public of places to do it.
Supermarkets, shopping centres, children's fun days - all of those places are pretty much "child must have tantrum" destinations.
Other classic tantrum times are putting children in the car. Sometimes they just don't want to go in and fight you all the way - crying and kicking.
Sometimes you get "the looks" from people that say "what a bad parent" or "what a naughty child".
No matter how frustrated you are with your child at that time, you simply cannot lose your cool.
