It's been like it for months, she's constantly knackered and her behaviour has gone down the toilet accordingly. But she just won't go to bed at nighttime.
We've tried lullabies and audiobooks, laying with her, blackout blind, lavender pillow mist but whatever we do she just doesn't go to sleep until around 9:30pm. I then have to wake her up for school in the morning and she's always so tired so the day always starts badly.
For context: She doesn't watch any tv on weekdays, most nights she comes to walk the dog with me and also bikes/scoots home from school so I feel she gets enough fresh air/exercise. After school we tend to just potter around, she does 1 club a week and has tea at Grandma's once a week.
