Ok my 4yo dd still has really baad tantrums, this does not actually bother me most of the time and they are calming down a little. What bothers me is when we see her friends she is really happy and excited (in fact absolutly hyper) as a 4yo should be. When we are at home with just 20mth old ds and me she just looks sad all the time. Even when we are out she walks around with the fingers of one hand in her mouth and her teddy in the other. She tells me she is not sad but I don't think she really knows what it means. I end up shouting at her just to try and snap her out of it which is not fair or nice (not often before you tell me off). I think she is fine at nursery, she just seems to hate our company.
