Noise cancelling ear buds. Apparently it’s really noisy in hospitals. Here are some other ideas off the top of my head.
Some of her favourite snacks so she can feel she’s at home or if the meals just plain stink.
Pyjamas or something else snuggly like stuffed animal to makes her feel warm and fuzzy.
Longer charging cord for her phone in case the socket is in an awkward place. A spare charging brick may be good too.
Crossword puzzles or other games to keep her brain active.
Nice tea bags, hot chocolate packets or coffee bags so she can have a better cup of hot something if the hospital options are dire. It could be her evening wind down.
An extra pillow perhaps
A favourite blanket from home. Or from your home!
Magazines
Lotion, face wipes, body wipes, and hand wipes to keep herself a bit clean when the nurses can’t get to her quickly enough. Mouthwash and lip balm maybe too.
A water bottle to keep her hydrated. A flask for hot water that the nurses or visitors can fill so she can have a hot drink when she wants.
Fresh fruit!! It’d be nice to have something unprocessed versus hospital food.
if I think of more I can post them later. By the way, you’re being a great friend. ☺️
