Second time moms.

I am pregnant w my second, 6 weeks. We are going to tell my daughter the week before Thanksgiving and then the rest of the family and friends on Thanksgiving day. But I'm trying to think of a cute, creative way to tell my daughter that she's going to be a big sister. I need some of your ideas! I am not creative at all and the most I can come up w is giving her this shirt haha..
