My (just turned) 10 year old son is currently in tears because I won't let him stay up until 9.30pm on school nights, I have said he can stay up til 8.30pm at the latest but he reckons that is the bedtime that "year two kids have, all of my friends stay up til 9.30!!!".
The current evening routine is along the lines of:
Dinner at about 5.30pm, watch T.V/play on the computer for about 45 mins then get to play with toys until youngest son goes to bed at 7.30pm, my 10 year old then comes upstairs at 8pm, gets teeth brushed and reads until 8.30pm.
He is my PFB so I have no idea of whether I am BU or not, he does struggle to wake up for school when he stays up until 9pm or later, he is currently chuntering away to himself about how unfair it is and how mean I am 
What time do your 10 year olds go to bed?
