Parenting a child can be one of the most challenging — and rewarding — tasks in a person's life.

Now, one doctor has shared some parenting insight that she claims can deliver a major payoff for families.

Dr. Becky Kennedy is a Manhattan-based clinical psychologist, a mother of three and the founder of Good Inside, a subscription-based website about parenting.

The tip? 

Kennedy advises saying to your child, "It can be really hard to be a kid, right?" 

By hearing that line of sympathy and understanding, Kennedy notes in her video, a youngster realizes that the mom or dad is seeing the world from the child's perspective.

This helps children be seen and heard — and can ultimately improve their behavior, she also said.
