A neighbours kid was recently admitted to hospital, and her parents packed a bag similar to mine.

Pajama trousers, long nightshirts.
Bathrobe.
laptop PC.
personal music player.
Cell phone.
Assorted puzzle books.

The child reported that they were well cared for, and the food was good.

Items not packed and later wanted. Bath towels because hospital one are "horrid", a wool blanket from home because "uncle Adam says hospital one are no good" and more books.
