Raining? Pouring?

For reasons that go against all odds and biology, Amelia has wet the bed roughly a billion times recently. Just yesterday, she consumed a single small juice box from the hours of 5pm until bedtime, pottied twice before bed, and still went Super Soaker 3000 on her sheets. I'm not even sure how that is possible.  A few nights prior to that, her bed was drenched and her pajamas weren't wet. Again, I'm not sure how that is possible unless she dropped trou and used her bed as some kind of really comfy urinal. Prior to this bad run, she had gone many, many months with no accidents at all. So, we're hoping it goes away as quickly as it came. Otherwise, we're going to have to replace her sheets with a rain tarp.
