Thanks for all the responses...
In my original post I hadn't had time with DD needing my attention, to give the background on the home situation. Now that I've had a little while to reflect on it and do abit of child psychology reading it makes quite a lot of sense that she is dramatically attention seeking.
Her twin sister is extremely special needs. Her mum is a single mum and there is no man on the scene at all. It's just the three of them full time (and a lot of helpers) . Sister has very little/few motor skills/cognitive ability (is unable to vocalise, walk, sit, feed self etc) and obviously the house is full of machinery/hoists etc etc and it's not a restful home. Her mother is AMAZING, stays calm and loving and makes as much time as she can for her able needs daughter to be with her one on one, but obviously the situation is extremely challenging for both of them :( It is not known from one day to the next, if she will survive days, weeks, months or many years... much unpredictability and th resulting need for improvisation with schedules etc.
DS's friend's presence in my his life has been (initially) very positive. He was extremely shy and withdrawn when he started at school and we had a huge struggle trying to get him to integrate in any level. Their friendship has brought him a lot of confidence and he is very well integrated at school.
But now that I see this extreme behavioural issue develop and it's effect on my son, I feel quite dismayed, for everyone involved.
She has been having sleep overs at our house because her mum finds herself at A and E with her special needs daughter being admitted for the night. What to do?
When I dropped her back off at home (mum can't come and get her at the drop of a hat) there were several helpers in the house and it didnt' feel like the right time so left it. The next call came, in the middle of a made hectic moment outside and I briefly explained that I wanted a quiet day with my own kids. I felt very respected and well understood. Later the same day an emergency call from the mother at A and E asking if she could stay the night. But of course..... what else to do? She does have quite a support network of trusted/trained individuals but I guess she's not always able to reach others and perhaps she wants to rotate requests for support so she doesn't drain any one channel.
I feel like just depositing the child back with her mother and saying the friendship is off would be a very difficult way to deal with the situation and not necessarily one that would be most helpful, for anyone concerned. Perhaps we can move beyond, without too much difficulty. If my approach changes from finger wagging and shouting and we're somehow able to calm the whole situation down and have some good talking sessions and fun.....?
Obviously I need to talk to her mum (when she's not calling from A and E or with a house full of physios etc etc) and I don't have a problem doing that at all. I expect a good healthy conversation. So that's the next step.
From what I've been reading, I could see if the situation could change with some positive affirmations of good behaviour etc, lots and lots of love and approval and cheer, which I must say she does get at home but under the circumstances and with a somewhat passionate/dynamic personality (and I suspect a higher than average IQ) isn't enough.
I started out with questions and this has become quite a processing channel...
I can see that I'm not ready to simply cut her off and wash my hands of the situation but I know that I don't want DS sleeping over at hers anymore. I would concede to sleepovers at ours however..... if I felt we were 'getting somewhere'. If not and nothing changes then it's time to give it a rest I guess.
Does this make sense?
Thanks!!!
