Over the years, I’ve thought a lot about young people’s reluctance to reach out to their parents when they need them. Ever heard a kid say the following? “I don’t want to tell my mom (or dad) when something’s wrong because they’ll flip out.” Kids and teens say this to me so often and it always worries me. But after an unfortunate experience I had a few days ago, I’ve been thinking about it a lot more.

Elijah, my older son, started playing middle-school football this fall. My husband was adamantly against it at first, so Elijah campaigned for months. After a lot of family discussion, we allowed him to play and one of the main reasons was we had heard incredibly positive things about the coach. He has that combination of toughness and supportiveness that middle-school boys crave.

Last weekend they played against an unbeaten team and finished the game tied—after three overtimes. The boys were devastated, but after the game, as the parents all stayed behind and listened to the coach rally the boys, I was so grateful that my son was having that experience. He was being told he’d worked hard and should be proud of what his team had accomplished, and to focus on what they all needed to do better next time.

That makes what happened next even stranger. As I walked down the field to put my folding chairs in their bags, one of the boy’s mothers verbally attacked the coach right in front of her son, my son and another player. By the time I got back to where my son was standing, the mother had walked away but her child was standing next to his father in tears.

I don’t want to focus on the details of what the mom said and whether it was right or wrong. What I do want to focus on is the serious impact of “flipping out” in front of our kids—especially when we parents think we’re acting on behalf of our child. I’d bet any amount of money that the mother who yelled felt she was being the “momma bear.” She believed she was protecting her child and only doing what was right. But beyond the negative impact of her behavior on the coach (this a common reason great coaches give up teaching our kids), she is guaranteeing that her child will never go to her when he needs someone’s help.

It’s ironic. When we think we’re most strongly advocating for our children, we assume that they'll see our behavior as being on their side. Using that logic, it’s natural that a parent would miss the obvious: Overreaction in any area of parenting (a problem with school, on a team, with friends) only convinces the child that their parent can’t be trusted to think through a problem calmly and strategically. What’s more, the child has good reason to believe that if the parent finds out about a problem, their involvement will only make the situation worse.

Probably every parent has had a moment when they’ve blown things out of proportion. I know I have. So what can we do? When we’ve gone over the top, we need to acknowledge it, first to ourselves, then to our children. We need to work on managing ourselves so that when we get worked up—no matter how justified we believe we are—we think through how we are going to communicate our feelings in a manner that gives the other person the best chance of hearing what we’re saying.

The mom at the game may have had a legitimate complaint, but because she conducted herself so poorly, the content of her words was lost. Her method of delivery was so inappropriate. If we think we’re losing control, let’s say it. As in, “Look, I’m clearly really upset right now, so I need a few minutes to get myself together.”

When we do things like that, take a “time-out” for ourselves, admit we made a mistake and tell our children that we’re sorry for overreacting, we’re going to do better and our kids will come to us. Why does this matter? Because we’re role modeling exactly what our kids need and want to see. When you make a mistake, you can talk about it. When you come forward and share a problem with someone you love, you’re a better person for it and your relationship is strengthened as well.

Have you ever “lost it” in front of your kid? Post a comment and tell me what happened.
