Belly Button!

Holy-moly my belly button just started to pop out tonight! Robbie and I were lounging around and he looked at my belly and noticed that it looked different. Upon closer inspection, it is about half the diameter it used to be, and you can see parts of skin around my belly button that used to be inside of it. It's so weird! When the baby book said my belly button could pop any day now (I am now at 22 weeks), it wasn't joking around!
