I'm only asking cos on another thread there are a few posters who've said their children have never had one. DS is 17 months and already has massive ones when he can't do something he's got his heart set on, like helping me stir a bowl of hot soup on the hob his own cooker but it's no substitute, or when he doesn't want to get into the car seat are typical examples. He's a lovely normal boy otherwise and is no trouble but am I doing something wrong?
