Have you ever met with an Occupational Therapist? Mine brought this catalogue of assisted living devices. I was amazed by how many products are out there.
I've got a set of large handled kitchen tools that really help with my grip issues. While I hate to be wasteful, I do use paper plates and disposable foil casserole containers to cut down on dishes. Well, really it's not that wasteful, since I was dropping and breaking my glass stuff.
There are things that can help with buttons and zippers, too. One of my favourite items are my Lock Laces. With my limited dexterity, I was having a heck of a time tying my shoes.
The Occupational Therapist came to my house, asked me what tasks I wanted to be able to do and suggested products and work arounds that might help.
