How to calm down a kitten
Tire your kitten out with play time.
Take the time to play with your kitten every day, multiple times a day if possible. Schedule some play time a couple of hours before you plan to go to bed and use that play time to tire, or tucker out your kitten.
If you finish playing with your kitten and find that she's still in the mood to play, direct her attention to a toy instead. Allow her to continue to prepare for sleep herself with a toy.
