Please consider what possible nicknames future classmates might find. Kids will be cruel, and they'll find something nasty to call anyone if they want to, but you don't need to make it easy for them. (And don't forget aobut the initials.)

Owen, Sean, and Gareth are rather nice for boys, and Aine and Alana are pretty for a girl. And before you name a girl something starting with a C/K sound, please consider this: among my friends there are two Colleens, Kathleen, Kelly, Kayla, Caitlin, Cate, Katie, and Cailey. (try saying them out loud) Gets confusing when we're all in the same room.
