I have two children that work full time and pay board.....one of the reasons that they pay is DH and I was to instil in our children that nothing in life is for free and you do have to work hard for things that you want.

They have a bedroom each of their own also.

I have cousins that have children also and when their children where younger and living at home they charged there children board when they began working.The parents where pritty well off and didn't need the money so they decided to open a bank account in the kids names and put the board in the account for when the decided to leave home they had the money there to get them started.
