This is what i did with my grown children. if they wanted to live at home, they had to pay room and board. i figured a fair, low, yet learning cost for that was $400.00 a month. But, instead of keeping the money, i put it in a savings account. when my child was ready to try wetting their feet a second time, i gave them the money i saved from the room and board. in one year they were able to save a good amount of money on their own, and when i handed them $4800 back, they didn't need come back. [Smile]
Well, they come back, but not to stay forever. just a night here and a visit there.
Hope this helps. It really worked for mine. Sandy
