We keep going back and forth on the order of the names. I want to incorporate Thomas in honor of my grandpa, whom I miss every day. Alexander is just a name we both like. (My husband has an uncommon name, and is set on giving a common name to our baby.) If we go with Alexander, we will call him Alex. If we go with Thomas, we will call him Tommy. Nicknames are subject to change as he gets older, depending on what baby likes.
