• My children have lied to me ever since they were young.
• This is a normal part of development as kids test the waters and try to avoid punishment.
• I've struggled to deal with the lying and tried to remain a positive role model for them.

It never ceases to amaze me how effortlessly my children lie. My 18-month-old, whose face was covered with crumbs, swore up and down that she hadn't been near the cookie jar. My preschooler looked me in the eye and denied breaking the window with his plastic bat that was still in his hand. It didn't seem to get better as they got older.

After I handed my ATM card to my two oldest sons so they had money for lunch, I asked for the change, and they said, "We only took out $5, so there is no change."

We all know you can't just withdraw $5.00. How could they tell me such a bald-faced lie with a straight face?

Dealing with my children's lies has been one of the most challenging aspects of parenting.

Lying is natural in childhood

Here's the problem: Lying is easy. What I find especially distressing is that no one has to teach children how to lie.

"Lying is developmentally appropriate," Ailen Arreaza, the executive director of Parents Together, a national nonprofit parent and family advocacy group, told me. "When a toddler or a 4-year-old lies, it's frustrating for the parent, but it's perfectly normal. It means that your kid's brain is developing in the way that it should be."

Arreaza also told me kids tell three kinds of lies: attention-seeking ones, careless ones, and serious ones that happen when they're older.

For example, one of my sons told me he missed curfew because he lost track of time when, in fact, he was at his girlfriend's house and just didn't want to leave.

"Often teenagers tell lies because they're afraid of the consequences or they're embarrassed," Arreaza said.

I struggled with how I should handle lying

Confronting my children in search of the truth is never comfortable. In fact, it can be exhausting — a round-robin of questions and denials before they finally break and admit what they've done.

There have been times when I was so eager to know the truth that I promised to refrain from any form of punishment. I want to hear a confession to satisfy my suspicion and feel vindicated, but then I face the sticky situation of what happens next time they lie.

"It's important to address the lie, but not in a way that shames the child and labels them as liars," Arreaza said. "This is about changing a behavior, not who the child is. Create a safe environment where truth-telling is encouraged. If they think they're disappointing you or they're going to get in trouble, they're going to continue to lie to please you."

I try to be a role model for my kids

I want nothing more than for my children to tell the truth, and often they do.

When he was 12, one of my boys came to me and, unprompted, confessed to a more serious lie he'd told previously. I had no clue, but it was eating him up inside. My son expressed his remorse and asked for forgiveness. I imagined the guilt was gnawing at him for betraying my trust.

I'm glad he admitted that he lied. In modeling the truth for my children, I hope they understand they can always come clean to me. My son felt safe and supported to do just that.

In that way, I have to believe that the truth will always win out in the end.
