This is so hard for me to reveal as I am really worried about my son. when we have issues with his behaviour and try to discipline him he laughs until he eventually gets upset and cry and scream and then to top it off he says he is so bad, bangs his head off the wall/door/wardrobe! it's so distressing for us all! when he was a toddler he did this too until he eventually grew out of it, we are at our wits end any tips or advice really would be appreciated. Help!
