Everyone wants to feel of value. They want to be included and they want to participate especially when they know they can succeed.
When a loved one is living with dementia or any challenge(s), at times they (like everyone else on this planet) may need a bit of help accessing something they know they can succeed at! Using a little creativity and a whole lotta playfulness (maybe a little muscle power too!) means that their contribution is absolutely what is needed to help out!
