Nursing every hour

My dd (5weeks old) wants to nurse every hour and would only latch for about 10-15 minutes then sleep (I'm trying to wake her up) if I try to change to the other boob, she wouldn't open her mouth and turn her face away from it. I wake up every hour during the night and it's frustrating. I'm trying to pump and feed her through bottle now and I can only pump about 70-80ml for 30 mins both boobies every hour . I just realized that if I pump every hour for about 30 and then feed her for about 10 minutes, my sleep will become shorter. What do you suggest? :(
