Umm, you better watch those first ones - isn't there already a My Child something-or-other? Or am I thinking of the Melbourne Child magazine?

There are the parents/babies/children expos running already, it might pay to check if you can use the last names on your list.
You might find it hard to appeal to teenagers, aim at the parents cos they will be the ones dragging them there!
I'd incorporate Family somewhere in the title.

gl!
