Hiya! Sorry to hear about your little kitten - Unfortunately there are no quick wins to getting a kitten to settle into a new environment. When they’re not snoozing, they can be very active due to their ancestors (wildcats) being nocturnal creatures.
You can try giving your buddy a main meal just before you go to bed, as cats do tend to sleep after a big dinner.
Also, ensure your kitten has plenty of activities throughout the day to keep her active; this may also help to tire the little furry out, so that you can sleep!
It will get easier over time as the kitten begins to grow, but it does take patience.
