Sophia has been crawling since she turned 8 months old (Nov 19)! It's thrilling and yet a little terrifying that at one moment she'll be across the room and reaching for the computer cord. We've taken quite a few steps at "baby-proofing" our house, and so far we haven't had to worry about her pulling herself up all the way or climbing steps (but this is right around the corner). We lowered her crib mattress the other day since she is able to pull herself up onto her knees. She is no longer just a tiny baby content with the small corner of the floor she's put in. Nope. She's a baby longing to explore! We hope to add some video of her in action soon!
