My father in law has parkinsons and now vascular dementia. He recently came home from a 5 week hospital stay after a fall. His wife is his carer she is a formidable force and independent capable lady but is elderly herself and already looks shattered after disturbed nights and falls out of bed which I think are the biggest worry for her. We are all keen to be there for her,. She felt she needed to give homecare a try as he is very against a care home or any respite but she would have everyone's support if she changed her mind. His condition became very serious quickly when the fall happened. it was not long ago they were on cruises and holidays together and enjoying a lively social life. He is constantly trying to get up (he has hospital bed in downstairs bedroom, Has a catheter and wears huggies (no continence pants provided) for now strictly not allowed to get up. I want to help but without being an interference or becoming a nuisance myself. Tips on how to help (quietly) but also read signs of when me or husband should step in/step up more will be gratefully received.
