I'm bribing my 12 year old. He doesn't get an allowance, but I told him last night that if he can keep me on track I'll pay him $1 a day.
Keeping me on track means:
*Going on a walk with me
*Making me take him (therefore me) to the Y
*When I suggest eating/snacking after 7pm, telling me it's late
etc, etc, etc.
He's game, I'm game-- it sounds like it could work.
