It’s a trick your kid learned in toddlerville: If one parent says no, ask the other one. While that was kinda sorta cute when your kid was trying to get an extra cookie, it’s kinda sorta not cute when your teen is trying to go to a party and you and your partner aren’t on the same page. As parents, you’re a team, end of story. That means having each other’s backs when there is a temporarily strained relationship between your teen and one parent in the parenting unit. There are no winners when families play sides.
