Your niece may not be your own child, but you love her just as fiercely. You find yourself catering to her wishes, doing things to make her smile, praising her at every opportunity. Family is a knot of people who love and support each other, and you will gladly lift up your niece as high as she wants to be. Let her know that you will be there every step of the way by sending your niece a festive birthday card.
