thanks guys for all the feedback. The good news is that I have decided not to go down the risperidone route for her. She is on Vallergan- the min dose every night and has gone from barely 8 hours of sleep a night (a good night) to consistently sleeping for at least 10 hours a night. She is coping much better at school (this is also combined with new strategies to deal with her behaviours), although the home front is a different story! Her support worker is also trying to put in an urgent referal for some psychological input, this time from hers and the schools perspective with what they have seen. So all in all I am thrilled that risperidone is no longer an option, and that she is sleeping so well every night. It sure makes a difference
