Now, your dad gets kind of uncomfortable when I show people the picture below and he probably won't like that I am displaying this for all to see... come to think of it, you probably won't appreciate it when you are older either... But, I am posting it anyways!
(Arrows have been added by me! Just making sure no one missed anything...)
So... just in case you ever have any questions, you are DEFINITELY a boy. Wahoo!
