Pulling up!

So I am sitting at the computer checking emails and I look over at Aaron who was just sitting on the floor playing beside me, and he had pulled himself up to standing by holding onto his bouncy seat!  I called Greg to show him and he said, "Oh yeah, he started doing that last night."  I hadn't seen him even try to pull up into standing position on anything yet!  Can't believe how fast he is growing up!  Seeing him next to Charlie really brings it home how much he has grown and changed over the past 8 months.
