Just finished our 9 month old check in class. Our girl Olive wasn’t the biggest or the smallest, but she was the fastest. Crawling back and forth and weaving in and out of chair legs, doing laps around the other 9 monthers.
Other things our Olive has mastered:
1) Crawling out of her car seat
2) Standing up in her crib. Below is the greeting I wake up to most mornings. 
3) Hanging out poolside. 
I imagine she is saying, Touch the crust and I break your thumbs.
