Our 12 year old daughter has always been stubborn and has had a temper to test the best. She has always had difficulties with friendships and cannot empathise with how others may feel. Yesterday, I found that she had invited and then uninvited a friend to a sleepover, after I had explained that the friend should be invited as this friends parents had arranged an amazing treat for them the following day. Our daughter was swayed by another friend who had told her I was being silly ( I have seen the text messages). I found out, explained that I was not happy with her decision and that she needed to invite this child. I got shouted out, escalation upon escalation until she caused £450 worth of damage to the shower. At one point she went out to the garden and I thought this was good, she, and I, could calm down, only to see her throwing the trampoline ladder around the garden and pulling the basketball hoop over - had to intervene to prevent damage and injury - so then the shower got it! Consequences were that the sleepover was cancelled initially and then she was withdrawn from the treat organised by the other parents as her behaviour escalated. On calming, I and then her dad and I, tried to explain that it was unkind to leave this friend out, we then established that the friendship (there are 3 girls involved) has been tricky for a few weeks, despite some lovely days out together) but advised her that this had not been the occasion to leave the one girl out. Our daughter cannot understand that by leaving this girl out she is doing to her exactly what she is accusing her of doing. I have always told my children that being kind has to lead their decisions. She has 2 older brothers (19 and 16) who are great with her, although the oldest is away at Uni. The 16 year old has traits of Asperger's linked to social ineraction and social imagination. Do we need additional help?
