I took the video below to show how good Jack's been standing up. He stands up at the footstool playing with his toys for 10 or 15 minutes at a time. It's so fun to watch him concentrate so hard on grabbing a toy that he has his eye on.
And this next video I took because I just had to get the sound of those giggles on video. Jeff had finished dishes and was just throwing the dish towel over his head, and Jack just couldn't stop laughing. That's a sound that will never get old!
