Sounds like what your DD is doing is pretty normal to me. Unfortunately babies don't really fit into our routines ever, even when they get bigger. No matter what anyone says, we do have to adapt even just a little bit for our kids. That long sleep in the beginning of the night is what she needs so I wouldn't suggest waking her up during this. Your nights could end up being much worse as a result. I would really suggest trying to get your body clock so that you can go to bed even an hour earlier and get much needed rest. Unfortunately our lives revolve around sleep with little ones! Good luck
