Staying United

My 6 year old has discovered playing one parent against each other.  I thought this wasn't something I would have to deal with till he is much older but it is becoming pretty common. It is partly my husband and I's fault.  We do a lot of ask mommy or daddy first or if daddy or mommy says yes it is ok.  This gets translated to Daddy, Mommy said Yes.  Can I go?  We have caught all of these instances but it can be frustrating.

My husband and I definitely need to choose our words more carefully and give the same response when asked.  Kids can be so tricky but parents can be tricky too.
