thanks for all these replies. I was up most of the night and router as usual playing up till now.
I've known this friend for about 30 years and she has history of depression. She's been in therapy, but to be honest, after 16 years she still seems 'stuck' in her difficult childhood. Her dc is 6yo (not her sixth dc!) and an only child. My friend had IVF and after a very long and difficult birth seemed to resent the baby who wasn't sleeping well for ages. She might have had PND but so hard to tell with someone prone to depression anyway. Whenever we spoke she seemed to resent me having such an easy time of it and having a really calm and easygoing baby. Everything has always been about competition with others and how her dc is doing compared to her cohort, and sometimes I've had to stay away for months as she's quite high maintenance emotionally (I live in a different city) and extremely critical too.
Her dc is bright and very serious and determined. When she was much smaller, the way she moved and spoke seemed like a miniature little woman and my friend said how she didn't know how to play with her DD. IMO she doesn't have learning difficulties at all except her mum loses it when DD doesn't do as she's told (not a good eater, doesn't like reading though seems like she's doing OK from my point of view) She used to be a very bossy child with an earsplitting scream and we were happy we didn't see them more than once or twice a year, but she seemed much better yesterday and now she and my ds played really well and a bit cheekily together. My friend says her dd has huge rages at home though is a model pupil at school. I said maybe she is angry and my friend agreed but suggested it was school that was the problem !
So behavioural difficulties, certainly.
Yes they are hitting to discipline but the way she described it wasn't just a small smack but manhandling and shoving and yelling etc. It could well be a cry for help and if i called ss - which i've thought of doing - they would just see a nicely kept, able, clean, child in a very comfortable middle class family who would cover it over. Agree I need to have serious discussion with her about this.
She's made appointment to see ed psych though they haven't got back to them yet, but even if if they could see the whole family dynamic was problem, what could they do? Fwiw i would say her own family drama being played out with this child and that they are both frightened of her.
Sorry about long post, I feel shocked though and want to get all relevant info down.
