DM is at the stage where she is fine living independently at home, can nip to the shop on her mobility scooter etc, but finding her way to hospital appointments is too much now. She refuses to take taxis and had trouble walking and probably wouldn't be able to fine the right department in the hospital if she hasn't been there before. She really needs to be escorted, especially when the weather is so cold. DSis isn't working the day of the next appointment, so will drive two hours each way to help. This isn't sustainable long term. What do other people do?
