My latest attempt is his allowance. Because I am So. Freaking. Tired. Of "Mom, mom, mom! Buy me xxx!!! Can you buy me xxxx???" Every time we go to a store. My answer, up to now, has often been determined by my level of fatigue and irritation. The more irritated I am, the more likely I am to say no. The more tired I am, the more likely I am to say yes.
Starting now, though, my answer is going to be "No, but you may (if it's appropriate) buy it for yourself." (Yay for spending money!)
N's allowance is going to be broken into two parts: a set amount he gets paid every week, and a set amount he can earn each week for a specific set of chores. Right now, since he's 7, I'm setting his allowance at $7 a week: $3 base, with $4 that can be earned by doing chores.
I struggled with the idea of paying him for chores. In my mind, chores are simply something you do to help around the house; you shouldn't get PAID for them. In the end, though, I compromised (yes, you can compromise with yourself).
N has chores that he is expected to do (no payment involved): make his bed, put away his clean clothes, put his breakfast dishes in the sink when he's done, etc. The chores he is rewarded for are the new ones I introduce as he gets older. As he gets adept at these "premium" chores and old enough to tackle different, harder chores, the old "premium" chores will become part of the non-reward chores, and I'll introduce new chores and new rates.
I'm not entirely sure how this allowance plan is going to work out. I realize that it's going to require a lot of monitoring on my part, especially in the beginning. Making sure that the new chores are done to my satisfaction, monitoring how much money he's actually earning a week, and reinforcing what he can do with that money (yes, he can buy things, but I also want to use his allowance to teach him to save, tithe, etc.) ... This new "strategy" is going to be challenging on both of us, but I strongly believe the rewards will be worth it.
Now it's just remembering the map! :)
