From puberty onward I made my mum's mornings hellish.
I am NOT a morning person. My braincells take awhile (like an hour) to get up the gumption to start firing, and sometimes even longer to rub together to get a spark. ((Unless it's some kind of emergency. I can be fully functional in 1/18th of a second if it's an emergency. Normal mornings just don't count.)).
As an adult, for normal mornings, I have my alarm set an hour and ten minutes early. It plays music, and I just shut it off over and over.
My son UNTIL puberty was Mr Cheerful in the mornings. But now that puberty has made it's appearance, he appears to have caught the curse. So I wake him up the way I prefer to be.
a) I give him a lot of time
b) I do it happy / loving/ silly
c) I bring in biology (OMG...I bet your reeeeeally have to pee! And just keep talking about needing to pee until he's racing for the bathroom. Bwahahaha)
When he's a bit older (he's 9.5 right now, my thought is 9th grade = time to learn how to screw up and fix it) I'll make him responsible for getting himself up. SURE he's going to miss a few days... but I'd rather have him learn that lesson when it doesn't really matter (highschool) than when it does as an adult in college/work/military. This is a conscious decision. My friends in highschool that were 100% responsible for getting themselves up and ready and to school would screw up occasionally (and their parents treated them like a peer... "Oh I HATE when that happens!"... because everyone does oversleep from time to time, so they had a mentor to bounce ideas off of instead of someone to fear)... but within a very short period of time, they were good to go and had ironed the wrinkles out. Myself and my friends whose parents literally drug us out of bed (or threw water on us, etc.) were drug out of bed all 4 years. We were never 'allowed' to make mistakes in our parents' houses... so we didn't learn how to be responsible for getting up until we were on our own. it really doesn't take very long, but it's a MUCH bigger deal when you're military, or paying for college, or can lose a job... then when it's first period.
