The last couple of months my son seems to be getting really frustrated and developing a temper whenever he can't do something and if he can't get his own way he has started to throw tantrums. For example he's got a walker which he loves and has become really obsessed with it to the point that if he sees it and I try to take it away from him he screams the place down. Also when he's playing with his blocks he's started throwing them in temper and the nursery have reported that he's been hitting kids when they've tried to take toys off him. I really don't want him to develop a spoiled brat behaviour. He's been ok up until recently. He's only 22 months. Could this be an early start of the terrible 2's or is this something I should be concerned about?
