Growing bellies have launched a growing trend–one that celebrates motherhood in all its phases. In the last month, The Talking Walnut has reported on more than a few companies making growth labels for expectant moms to affix to their clothing in proud proclamation of their soon-to-be new arrival. Whether you are three months along or in your third trimester, it’s a fun way to announce your pregnancy progress–and a clever means of putting a stop to all those unsolicited inquiries. If you’re more inclined to profess your thoughts on your belly itself, then we may have be just the venue to share your feelings. The Million Moms Challenge, along with ABC News, the United Nations Foundation, Disney Baby and Anne Geddes (phew!), is holding a photo contest for soon-to-be new parents. Dubbed “Imagine You & Me,” the contest invites women in their third trimester to upload a picture of their baby bump, featuring a handwritten, creative message for their little one, on Facebook. Entries will be accepted from now until December 4, 2011 at 11:59 p.m. EST, and will be judged between December 6-15. The winning entry will be announced by famed baby photographer Geddes herself on ABC News on December 16. The grand prize is a trip for two adults and their lucky baby to Australia where they will be photographed in Geddes’ studio in Sydney. So grab a marker and start thinking about what you’d like to say to your bundle of joy before she arrives. Good luck!
