In a lot of families one parent has to travel. It could be a business trip, visiting family, or a military deployment. And at times, one kid tries to play the parent left in charge. So, what do you do? Make sure you’re on the same page about rules and communicate your expectation that the kids cooperate with the remaining parent. This is really important in stepfamilies if the biological parent is the one leaving the home. Then, parent in charge, stand your ground, and follow through.
