There's water in my BED!!!!

Rileigh comes into our room at 4:30 AM..........which is almost never good....Mike ask her 'what's wrong?' she says nothing...so I ask her 'Rileigh, what's the matter?'..Her reply "there's water in my bed" which is code for 'I wet to bed'!! Poor thing didn't want to admit that it happened to her! I'm hoping she was so exhusted from swimming for hours on end that she just simply didn't wake up this ONE time!!
