I cannot lie: The last couple days caring for my grandsons around the clock has been a bit of a challenge. Why? Because Baby Mac has got to be the most strong-willed bundle of energy I have ever come across.

Baby Mac's steadfast determination to keep up with brother Bubby—who will be four years old in June, compared to Baby Mac turning one year old the same month—has kept me hopping, to say the least. He thinks he should be able to do ab-so-lute-ly everything his brother does, despite lacking not only physical ability but also the common sense to know such feats at his age are sheer lunacy. And when I prevent him from risking life and limb in pursuit of his goal, Baby Mac throws fits reminiscent of my biggest battles with my daughters during their teen years.

Every once in a while, though, Baby Mac chooses to imitate his brother in something that isn't dangerous. For example, after watching Bubby place the ball on his T-ball stand several times, Baby Mac decided to give it a try himself with his own ball. This was the result:

Baby Mac's enthusiasm and obvious pride in himself for succeeding at the task at hand is exactly how I will feel, possibly even how I will babble, once I manage my own task at hand—that of making sure the little wild child survives safe and sound while his mom and dad are away.

Today's question:

What are your challenges—and successes!—of the past week?
