I've always wiped front to back, and maybe that's weird, but it's still difficult for me to do now, haha! Baby's always chillin' in my ribs, but I figure she can manage a second or two of squishing.
Now, the peeing in a cup thing--THAT is a problem! Not sure if PP was suggesting doing this from the back, but I had never thought of that! I'm trying it tomorrow! Haha. It is definitely not nice to pee all over the dang cup--they're so friggin' tiny.
