If you're still waking up to pee'd on sheets I have one question for you... WHY? There's a perfectly perfect diaper out there so you can stop all that drama. Unless you just like washing pee'd on sheets. I mean... do you? Of course you don't. So stop already. And get a better diaper. And by better diaper, I mean THIS diaper. It can hold anywhere from 18 to 31 ounces. That's almost 4 cups of pee.
