Also on Father's Day

My baby lost another tooth. He lost his first two teeth last year over the 4th of July weekend and now nearly a year later, he lost another bottom tooth. Though I'm pretty sure he helped pull it out. Now the two top teeth are rocking. My baby is slowly morphing into an adult or something. Can't adult teeth come in later, you know when he's closer to being an adult? When he's about to get married?
