My new favorite thing - sitting up

It's amazing how up until three weeks ago, all Tesshin could do was roll over - back to front, front to back. Now he can crawl and he's all over the place. We've confined him to the living room but he found his way through the hallway and into the bathroom today. He also made his way into the kitchen. Now, our house isn't huge, but I can't believe how mobile and quick he's become. He also can crawl for a while and then sits up without using his hands to prop himself up. He also likes to pull himself up on his knees. Sometimes, he can get up to his feet but it's not consistent yet. It looks like he's ready to get up on his feet and walk but he has to learn to lift his legs up. He's only been home for a week but he's accomplished so much. If we can only get him to use a teething ring!!!
