Brendan's new tricks

Before I relate the latest with Brendan, let's review his current status. He's a good little scooter/slitherer, but not much of a crawler and not a great sitter. He attempts both crawling and sitting, but needs a good amount of practice before he can handle either. Now, lately, I have noticed him slithering up to different things around the house that are above his head and just looking at them... I could practially see the wheels turning in his little head. Then yesterday, he slid up to a chair in my bathroom, reached up, grabbed the seat and pulled himself up onto his knees and grinned at me. Today, he pulled up to his feet. Its like he can't get one skill mastered before he moves on to the next. I wonder what this indicates about the future!
