Grandpa, will you bring us your tools?

I walked in to get Mason up from his nap today and, boy, was he up. This was the first time he has stood up by himself in his crib and, by his expression, he didn't seem to understand the gravity of the situation. It was just at the beginning of August that Grandpa lowered the crib some because Mason was getting up on his knees. Now we will have to lower his bed to its lowest setting before Mason starts to crawl out of it.
