They also like to wait until 10 pm to ask for homework help/printer ink/poster board.
Boy-oh-boy-oh-boy! That drove me insane. Especially when you ask them before dinner (at a decent hour) if the homework was done, or if there was anything that they needed for school tomorrow.
I'm a "mean mom" about this. My kids get ready for bed at 9, lights out at 10. They very rarely forget to do homework but when they do it's "Do you want to get up early or do it at lunch recess?" I've let them stay up a little bit late if they couldn't
get the work done by 9. (Like if we've been out for a family function)
The other night DD comes to me at 7pm on Sunday:
"Mom, I have a ton of math, I might have to stay up late."
"You've had since 4pm Friday to work on that, bedtime is 9."
"But my teacher doesn't accept late work!"
"Then you'd better get started."
