Large, soft, huggable Teddy Bears. Baby sized dolls with clothes and blankets. Men and women both love them.
My DH was in a nursing home for his last 3 years, and I discovered that a lot of the residents who were stroke/brain damaged wanted something soft to hug. Some of them actually carried around rolled up towels held together with rubber bands.
I got a bunch of big dolls at Walmart and dressed them, the workers there told me which ones would be good "Mommies".
I saw them around for the entire time DH was in there.
Ask someone who works there what they need or want.
