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.
