A friend of mine has been regularly coming to our house for about a year. She's the same age as my youngest child bar three months. In that year, she won't let her mum use the toilet without her, won't play with my two children (4 and 3), won't be without her wellie boots, won't be without her coat, and won't play with my children (although her mother does tirelessly). We went to her mother's 40th party on Monday and she was much better there. My sister was a nursery teacher and now is a childminder who looks after a girl who's 8 and has only just been diagnosted with Asperger's. I find it incredible that she's slipped through the net for so long and wonder if my friend's child might suffer the same lack of interest. What should I do? She suffered many miscarriages before this child and I'd hate to mention any possibility about my misgivings.
