The terrible two's have hit our house! He started nursery a few week ago and since he has he won't listen to me, it's like all the rules have gone out of the window. He hates to be in his pram and will scream the whole time but if I let him walk he runs away. By tea time I feel like I'm ready for a nervous breakdown and feel like I am constantly shouting at him and feel like a horrible parent. I just don't know what else I can do about his behaviour??
