sleeping beauty

For about the past 2 months, Banks has been getting up only once during the night (usually around 3:30am) then goes back to sleep pretty easily after a snack and sleeps until 8:30am.  Well, I am not going to get too excited yet, but we may be turning the corner on sleeping all night.  3 out of the past 5 nights she has slept all night long!  The first night was Friday and I woke up in a panic when I opened my eyes and saw the sun outside my window.  She had slept from 9pm-7:50am!  Then the past 2 nights she has done the same thing!  She kind of stirs around a little bit between 4am-5am, but goes back to sleep without us even going in her room.  I'm not sure what I'm going to do with all this extra sleep...ha!
