I don't know if the two are related,but my youngest ds has been really difficult in the last few weeks. His preschool are calling me almost every day to tell me about some wild tantrum he's had. Today they said they had to clear all the other children out into the garden. He is also very emotional at home. I can't get through to him at all. I thought it was just a phase as he's starting school in September. But I am more concerned now as the Preschool want to film him. They think it will help them figure out what the problem is.
