As of today Gavin has been with us one month! It really flew by. Today for the first time I found Gavin sitting up in his crib. When we first got him he couldn't sit unsupported or sit up on his own. He became strong enough to sit unsupported the first week, but it took longer to learn to sit up. I did "occupational therapy" with Gavin everyday to teach him to sit up on his own. Looks like it has paid off.
