Early rising 7 year old

[miabl2]

My 7 year old goes to bed 7.30/8 on week nights but has started waking at 5ish and can't get back to sleep. Are we putting to bed too early? Advice/ideas please

He does play or read in his room till 7, more worried that it's not good for him to start his day so early and wondered if bedtime acurate for his age. Dead quiet area.

My 7 year old sleeps for roughly 10 hours,but I reckon at times she could do with more if thats any help.

He seems okay with it bit teary sometimes. Always put him to bed same time as his brother (4) will try 8.30 tonight and see if it helps
