Following onto my bedtime routine post ...what time does your kindergarten child go to bed? How many hours of sleep does this give them?

My child is supposed to be in bed at 7:40, so asleep by 8. She gets up around 7-7:30, giving her about 11-12 hours of sleep! Lately she’s been wanting to be up later, though, which makes me wonder if I’m trying to get her to bed too early.
