Including school holidays and weekends?
My twins are 4 (almost 5) . I find that if they don't have enough sleep they are grumpy, rude and uncooperative the next day.
They also get up at 6am , no matter what time I put them to bed !
I can hear children out playing in the sunshine and one of my twins is already fast asleep 
The other is in bed quietly playing a game .
I selfishly enjoy my evening time and as I go to bed myself around 9:30pm, I like to keep them in routine so I can have some down time .
But I'm not sure if this is mean? AIBU?
