Dd has been going to pre-school since she was 2.7 yrs. At first she screamed every day and had to be taken in by one of the teachers but after a few weeks she was fine. She's started doing it again for the last few sessions. Mum (who takes her) asked her keyworker if anything had happened to make her do this but she just dismissed it. Mum asked a different teacher who is going to talk to her today. She won't tell me anything and the only thing she's told mum is that she's bored. Do you think being bored might cause this?
