A large study of teenagers found that as brain develops, it trims away excess cells so that what's left is more efficient. One of last parts of brain to complete this process is prefrontal cortex, which controls planning, judgement, and self-control. Many teen-agers have not experienced "maturation" of this part of their brain.

"[Adolescents] are capable of very strong emotions and very strong passions, but their prefrontal cortex hasn't caught up with them yet. It's as though they don't have brakes that allow them to slow those emotions down," said Charles Nelson, a child psychologist at University of Minnesota.

Researchers say this may help explain often irrational behavior of teenagers: mood swings, and risks they're often too willing to take.

"If I walk into a class of kids who are 14 or 15," said Nelson, "those kids have a level of brain maturity that just does not map onto kinds of emotional decision- making that a lot of those kids are being asked to make by teachers and parents. Added Nelson: "The more teachers and more parents that understand that there is a biological limitation to child's ability to control and regulate emotion, [the more] they might be able to back off a little and be a bit more understanding."

It can be quite easy for us to judge our kids harshly. But when you can begin to enter your child's world and consider developmental limitations that exist, call to a kindler and gentler way is undeniable.

Your kids will continue to make mistakes.

Your job is to stay calm, love them, and gently show them a different way.

And to be thankful that your kids are here to challenge you to become a more patient person.

Even a person with Alzheimer’s Disease can often share stories that others may think are lost. If she can still speak, put an item in her hand, and it may remind her of events or uses, people or places. Ask her questions, and you may get more history than you expected. Start now to preserve those stories, histories and ways. Give or request a loving legacy for any season or occasion.
