Parents know all about the verses related to how children should behave but not so much about those that remind them about how they should behave.

~ Jeff Vanvonderen

I cannot make my kids obey. But I can control my responses to their disobedience—that is, I can respect their choices and provide wise consequences for their actions, so they can learn just as much about wisdom from disobeying as from obeying. And I can respond in ways that create an environment in which their poor choices are their problem.

In other words, children's choices are their responsibility, and result from how they decide to meet their own needs. Once you understand this, you can learn to stop interpreting their choices as statements about you. When your kids act weird in front of the in-laws, it is about their choices, not about your value as a person. Grace-full in-laws will already know that. You need to know that too. Otherwise, you will parent to fix your kids, so that when they are fixed, you are fixed. You will parent to control, not to serve. How things look and what people think will become more important than what is real.

~ Jeff Vanvonderen

Your children should not have to act appropriately so that you can feel like a valuable person. It is not their job to validate you or erase past relationship indictments against you with their performance. In a healthy Christian family children are not there for the adults, adults are there to be resources for their children.
