For the last several weeks, Seth's been getting up on his knees, and scooting around all over the floor when I set him down. He seems pleased with his new found mobility, however, I've been hesitant to classify him as a "crawler" just yet as I don't want to come across as one of those parents who says things like "my 3 month old can read!" He's definitely movin' and groovin' though, that's for sure. Then one day last week I sat him up on the floor because he was not happy lying down, and to my surprise, he can sit up by himself too! He's growing faster than I can keep up!
