DS is 3.8 and in the last couple of weeks has gone from being good most of the time to being a complete brat. A lot of the time he's fine but several times a day he'll totally overreact to something and will get himself into a complete howling rage. I've just never seen him so angry and any little thing will set it off. A minute or two later he'll be his normal happy self.
Please tell me this is what kids of this age do and I'm not going to end up on Supernanny in a couple of years.
