what is that smell??

We were out back enjoying the pool. I kept getting a whiff of something stinky, but it always seem to happen when Gracie walked by. I kept blaming it on the dog, eww Gracie you stink. Get away! Haha When it was time to go inside I bent over to get Allie out of her exersaucer and wow! The Smell! It was Allie the entire time. There it was running all down her leg and all over everything. This definitely warranted an afternoon bathing! Yuck!
