Before my friend had her daughter a few years ago, I had no idea that the likes of this even existed. It's a belly button ring designed for pregnancy! The barbell is long (and you can get ones even longer than this) and made of soft, flexible plastic, so that even as your belly stretches and contorts and does the weird things it does in pregnancy, you can keep the piercing open without pain or fear or your body pushing the jewellery out. Genius. I love it. And they're just so cute! Look at those little dangly baby feet... squee!! I also got one with a little giraffe charm, and a plain one incase the dangly bits were irritating me. Very very happy that these exist.
