Preston's 2nd tooth and formula (7.5 months)

We've got another tooth poking through already so now the lil' guy has 2 coming in on the bottom right next to each other. He's our happy monkey and is weighing in at 19.2lbs. He spends most of his time exploring on his tummy, army crawling across the room, and chewing on anything he can find. He's transitioned perfectly to formula and doesn't seem to notice the difference!
