My 2yo daughter is the same. It takes like 20min to catch her running around, then another 10min to dress her in the Pyjama. After reading her a Story she's like:

Ok what's next 😀 then she starts humming some tune, grabs some book to look at... and then suddenly dozes off 😅 it's annoying but hilarious, really.

Don't you dare change something - then she refuses to cooperate and is stubborn as a mule.
