Brittany and Mikey are known around here as "the middles." They are 15 months apart, stuck in between our two other kids. They are joined at the hip most of the time. They have conversations that we can't follow. They play games that we don't understand. They hold hands and walk through the yard for no apparent reason. Mikey calls her "Britt" and Brittany calls him "Mike." I believe they will be lifelong friends. It's been really cool to witness over this past year.
