We are 10 months old and officially crawling. But at 9 months, we could move around just find by rolling around. Here is a video of our rolly-polly adventures.
Some updates:
We've been eating cherrios all by ourselves for about a month. We can go from sitting to crawling and crawling to sitting. We like to say "Ga-ga-ga, Da-da-da, and Ma-ma-ma"
