Take a few changes of loose, comfy clothes, PJ's, dressing gown and slippers. The ward washing machines can be very basic so try to stick to cotton and fleece.
If you have a brand of washing powder you have to use because of allergies, take that and write your name in marker pen.
Wash things, shampoo, hairbrush, toobrush and toothpaste, sanitary protection.
Something to read, a couple of books, a kindle and charger, headphones, phone and charger (put some credit on now if you can), and some pens. The occupational therapy staff can always get you some puzzles but pens can be like gold dust.
£20 or £30 in small notes and coins if you can. It will go into the ward safe along with your keys and bank card, and you sign it out when you need it.
There's usually a shop and cash point somewhere in or near the hospital, and a coffee shop or machine. If you run out of cash a member of staff should go with you to the cashpoint.
If you cant leave the ward to go top the shop yourself, a member of staff or trusted patient usually do a run once or twice a day.
They may search your bags when you go in as some items will be banned, eg some kinds of footwear such as steel toe caps. They will ask you to hand over all your meds.
Some wards don't allow any glass or china, so if you take your own mug (I recommend it) it needs to be bamboo or melamine.
You can take snacks but you aren't always allowed to have them in your locker, so if you have a cool bag or tupperware put them in that.
There might also be a library, they might come round with a trolley and you can borrow and request books.
If you have any problems then the PALS reps should come round once a week.
