Anyone dealing with this?

Mr W (3y5m) never takes no for an answer and is always looking to split the difference.

For example. He lost some privileges earlier in the week. This morning he talked to DW on the way to school.

"Mommy, we need to talk."

"Yes, dear?"

"I want to do XXXX."

"Well, you lost XXX when you were bad."

"But, Mommy, that was just one day."

"But we told you to listen and you hurt XXXX."

"But, Mommy, I was good the other practices before that..." (Proceeds to list the days and dates.)

"Yes, but you were still bad.."

"I think those good days should count."
