You have teeth! Your bottom two front teeth appeared exactly one week apart.
Your blocked tear duct cleared up!! (YAAAAYY!!!)
You're still not crawling. However, you have learned how to go from laying on your stomach to sitting up. I fear that this new skill will hinder your crawling abilities though. Every single time I lay you down on your belly to practice crawling, you immediately sit yourself up and show no interest in moving.
