Trouble sleeping

[Kim2017]

My 9 year old daughter is struggling to sleep through the night. It started a few weeks ago. (only sleeping through the night 2-3 times during these few weeks )

Shes been going 2 bed ok, she does have a habit of calling out for the first ten mins, then drifts off.

But almost within no time at all of me getting into bed, shes awake and walking into the bedroom. this can happen 2 or 3 times a night. and im exhausted.

Does anyone have any tips ? im hoping the back to school routine will help her sleep return to normal.
