Give her a sensory bin of cheerios. She can eat them, crunch them, throw them, hide them, find them, dig in them, string them, make shapes out of them etc, etc... It's a low effort, high interest activity, and a go-to for when I was sick with littles.
Mine loves pots and pans, the vacuum, anything that’s not a toy but safe basically lol
Making laying down part of the game - she can draw round your palm, or pretend she’s your doctor, or you can only guess the animal sound she’s making with her eyes closed, stickers on a box by your side?
