Myolive13. I'm glad you found us. I hope you will make yourself at home here. Olive sounds like a beautiful and healthy girl.
It's unfortunate that she is keeping you awake at night. Kittens do tend to be more active. There are a couple of things you can do to get her to sleep during the night.
One thing that helps is to give your kitty a snack before going to bed. The other thing which is a great behaviour modification tool is Interactive Play. If it's possible a few 15 minute sessions of interactive play per day. Slow things down towards the end of the session, especially the one just before bed, followed by some food or treats. Here is a link that explains how to do interactive play.

It may take a few night sessions before Olive will sleep, as behaviour changes don't happen over night.
Good luck and let us know how things go.
All the best,
