We have had some action
Our SWA phoned before we had to go to the appointment this afternoon. Her collegaue has passed on all I had told her yesterday (but I didn't use the words "We don't feel we can care for him at home..." as I had planned before his fall) but I ended up telling the SWA everything, about our pig of a weekend, our fears about the holidays, the bruises and bites and the attacks on DD etc. She said she will take action immediately because when a family says "we don't think we can cope at home anymore, they listen! So those of you who said that, especially lovely JimJams (who is an oracle on SN anymore ) were quite right!!
She said that he would need 2:1 direct payments carers and she would get right onto it. She would also phone the respite centre to see if they had any cancellations in the hols.
Then we went off to see physio and whilst there, the paediatrician came out to waiting room to intercept us (!) in response to my message about the resperidone and took us into her office and we had a good chat. She said she would be happy to prescripe; this said as DS tried to bite through DH's arm. She was very interested in meeting DD as well and hearing her views on what she goes through at the hands of her brother (shes#'s never met before.)
We came away with a prescription. I've dropped it in but can't collect it until 10am so hopefully he'll still be able to start it tomorrow. It's a very low starting dose that we can increase after a week if we think it is having a little effect but need more.
Then SWA rang back and said she'd got authorisation for sixs hours TWICE a WEEK for us throughout the hols, with two at a time direct-payments funded carers! She has to finalise the arrangments tomorrow and we have to have an assessment but she was very certain about it.
After the hols it will be six hours once a week, but still a lot more than we've ever had.
Thanks so much for the support and good advice provided on this thread.
Podsquash, we have done lots of alternative stuff over the years to varying degrees of success but can no longer afford it but thanks for the suggestion.
