Fun ideas for play den

[WhatNext24]

Hi all, my little niece who is 5 just got her first cabin bed with a little space underneath that has a curtain and is like a little den / tent. With Christmas coming up, I'd like to get her something to go in the den. What would be fun for her do you think? She already has cushions and fairy lights. It's quite a small space but just wondering if any mums of 5 ish year olds might have ideas. I have no kids if relevant.

Chalk paint so you can paint the wall for her to draw on.
A giant white board to draw on
A projector to watch movies.

ooh, all good ideas to look into - thank you @FunLurker!

Glow in the dark stars to stick on the underside of the bed. Extra fun with a torch to get able to charge them, we found they didn't get much light under the bed but the kids liked to focus a torch on a few at a time to make them really glow.

Wall decals of whatever she's currently into.

We got lots of use from a little star projector from Amazon.
