She’s 9, she’s quite grumpy without sleep, we have to get up at 6.45 for school. Usual bedtime is 8pm (lights out) - bake off finished at 9.30. We usually watch it a day later on catch up.
I’m just going to bed and I can see that one of her friends has stayed up to watch it and now I feel like a meanie!
