My DC7 and DC5 go to bed around 7pm. But sometimes have a later night on the weekend so Sunday night can even be as early as 6.30pm. They fall asleep quickly. DC7 wakes up at crack of dawn at 6am-7am no matter what - even if he went to bed at midnight it wouldn’t matter. He’s always needed loads of sleep. DC5 can cope a bit better.
Someone made me feel like a bit of a cruel DM the other night for these bedtimes - their DCs stay up a lot later. In fact on Sunday nights in summer their DC5s are still out playing gone 7pm.
I don’t feel insecure in any way about it. Mine just cannot cope with late nights especially before school. To be fair I go to bed at 9pm ish! But I’m just intrigued about what the range is for other children?
