My W wants me to assist her in waking-up. I approach it as I'll wake her up, if I'm up, but otherwise she's on her own.
This is a little confusing to me. Will your wife know when you plan to wake her up and when you don't? Just saying "if I'm up" is the part I don't find helpful. Even my D17 relies on me to get her up for school, but if she has somewhere to go during the summer and she knows I will have already left for work she gets up ok on her own. You're your wife's security.....she just seems to demand things from you instead of appreciating what you do.
I like Lanzo's idea of waking her up with a tray of coffee or tea (add a flower for good measure), but I would think you would need to feel you were doing that out of love instead of because she "demands" it. That could be a nice surprise one morning(just not after being scolded for not waking her up when it's not really your responsibility)
