OT

I have a Prolapse Interverbal Disc and Degenerative knees i live on the second floor without a lift 33 steps all the way to my door, i live with my two kids 3 and 10 years. My 10 year old is ADHD diagnosed and isn't able to share a bedroom with his sibling as he constantly fidgets on their bunk bed and has sleep difficulties takes hours to fall asleep. My son gets child DLA and we're waiting for an OT from our local council to give an assessment. I know he would be entitled to his own bedroom but what would be the likelihood of him getting his own bedroom? i am on Band B but i have a solicitor trying to get my banding changed to band A as the stairs cause me extricating pain. I just need advise to know what could be the outcome of the OT
