A Boy or A Monkey?

Over the past few weeks, JP has been working on his climbing skills. If things get quiet and he's out of our sight, we find situations like this:

and this:
But, the worst/scariest was when he climbed the ladder to our loft. It's a real ladder and he was two rungs from the TOP when I found him! He was so very proud of himself, he just grinned ear-to-ear while I froze in fear...then, started laughing and considered running to find my camera. But, since he was a good 6 feet off the ground, I figured it wasn't a very safe photo op!

Here's the ladder, and here's my redneck solution to prevent him from climbing it anymore. Does anyone have any other suggestions???
