I read this thread and didn't have anything to post because I couldn't remember when my girl stopped her early morning piddles. I felt bad for you b/c I did remember feeling like I had a baby, up every a.m. at 4-5.
BUT, the last two nights I have been up twice! around 1-ish and 5-ish b/c she decides she needs to go out. I thought of you while dragging my butt out into the cold dark night this morning!
So, it will get better...but hopefully stays better...for you
LOL
