Sadie is 9 months old

Sadie turned 9 months this week. Wow! She weighs 18pounds and 4 ounces. And is 28 inches long. She is backwards crawling and scooting and rolling, twisting, and turning to get where she wants to be. It is funny to watch. I want to say to her forward crawling would be a lot less strenuous. This morning, she backwards crawled from one end of her room all the way under her crib with just her head peaking out. Hysterical!
