Lots of pictures of family etc, and put them in frames, the ones in boxes/albums never get seen.
Chocolates and sweeties, basically goodies that don't go mouldy.
Some nice scents, everyone always seemed to have lavender scented stuff, so clearly thats the fashion for the elderly
Large print books
Cord for her glasses (they ALWAYS get lost in homes)
And if you are feeling a bit practical go to BonMarche and go to town on new knickers, vests, nighties, tights and clothes. And label them for her, with her full name. Clothes in homes get trashed, they get washed at all sorts of funny temperatures and whites etc are not separated. Anyway we were always pestering families to buy more clothes, particularly underwear for our residents.
Maybe a cheap CD player with some classic CDs, or just a radio?
A nice clock for her room with a large dial.
A calendar with important dates marked on it (birthdays etc)
Hope this helps. Some of them are a bit boring, but honestly a lot of gifts bought for our residents sat in drawers unused , oh and don't buy scented moisturisers, it never gets used IME. The home will just use E45 on her.
