both my kids have been with me since birth (and i have the stretch marks to prove it) and at age 9 and just shy of 12 they still engage in power struggles.
my current 'power struggle' with ds 9 1/2 is if he is 'put to bed' at a reasonable hour but can't get to sleep and as a result ends up flip-flopping his sleeping pattern (up until 6 am, sleeps until 4 pm)-does the 'only mom/dad can microwave food rule' extend to waking mom/dad up at 2 a.m. for 'dinner'

if i have to endure another night of being shaken awake with a request for 'nachos-cheese, refried beans, olives only' i'm gonna die!!!! (note-if you look at alot of my posts this summer they are in the middle of the night-cuz despite refusing to run an 'all nite diner'-once the kid wakes me up i can't get back to sleep!).
