My sweet sister (in law), wife, career woman, and mother of three scrumptious boys decided a few years ago that her plate wasn't quite full enough. Being the over achiever that she is, she created a product for pregnant bellies called, Bump Bows.
It is an adorable "bow", made of medical grade materials, designed to cover a pregnant woman's belly button. This adds a layer of protection and comfort for those times when your button gets a little uncomfortable. As a photographer, I will say it is also a pretty fun reveal tool! They come in three colors and can be ordered for yourself, or as a gift (raise your hand if you know any pregnant women).
