how long does feeding routine take you during the night?

My little guy is 3 weeks old. Between diaper change(s), eating, burping, and sometimes attempting to wake up for the other side, it's taking me anywhere from 30-60 minutes each time I'm up with him. I'd say the average being 45-50 minutes. This seems to be working, but sucks a little bit. Sometimes it's hard for me to fall asleep after being awake for so long. And then I'm back up again in 2 hours-so at best getting an hour and 50 minutes of sleep, which is really being generous since he's often stirring in his sleep keeping this mom awake and alert.
