i don't think it's enough to "merely" be a photographer. has your family seen any photos that you've taken of babies? not everyone is aware of the various techniques that some photogs use for baby pictures—the baby nestled in something white or being held my mommy or daddy, also in white, with soft natural light coming from a window off to the side, etc etc. if you can show that you know how to photograph babies, then i'm sure you'll get the "assignment." haven't you ever shown photos to family members and they say, "whoa! i didn't know you could take pictures like that!"? take beautiful photos of a friend's baby, show them to your family, and make them jealous!
i was asked to take photos of cars—something i don't know much about—because i have cool pix that i took of cars in my flickr account. sometimes people really need to see what you can do.
