Tammy or Tommy?

Today I got two more name suggestions! One of my Grade 6 students came up to hand in her assignment and randomly remarked, "I've got names for you." This came out of the blue, as she hadn't said anything about me being pregnant. My first thought was, "What names? I want your reading log!" but when I asked her, she clarified and said they were for my baby. Tammy for a girl and Tommy for a boy. I assume she'd want me to use both for twins. Hmmm... I'll get Dean's opinion on this.
