Help with Double Announcement!

Ally
My sister and I are both due at the end of July. This is my first, her third. We're American, but I live in South Africa and she lives in Israel. We're trying to come up with a cute/sassy/ridiculous double pregnancy announcement for Facebook. We have matching maternity dresses that we can wear for a side-by-side photo, but we're definitely open to ideas. What should our tagline be?
