Yes, it's hard to have to say "no" a lot. Of course, there are good reasons to feel you must do so. People with moderate-stage dementia often want to do things that are unsafe or beyond their current abilities, or that are simply inappropriate, ill-timed, or infeasible. And they lack the cognitive wherewithal to understand that these wishes aren't always possible. Your goal: to preserve an upbeat, encouraging mood while still managing to set the limits the situation demands.
Here are 10 alternatives to "no" that you can try weaving into your vocabulary:
I wish we could!
Wouldn't that be nice?
That's a good idea; let's try to plan something for later.
Would you really like to do that? I didn't know that about you.
I think it's too hot/cold/wet today.
That sounds like fun for next time.
That's an interesting idea to think about.
Oh, I can just imagine that.
Really? You have so much energy/enthusiasm/imagination/curiosity.
I think I'd be more comfortable doing X; sound good?
