To me it sounds normal. your baby might be going through growth spurt. I remember having to feed my son almost every hour during that period of time and it lasted almost a week. Anyway, NB babies dont't drink a lot and since breast milk is easily digested, they get hungry often. I dont't really know how to stretch night feed as I feed on demand. Helps to boost my supply.
Alternatively, you may want to express your milk and let someone feed your baby so you can rest. But you must not miss any sessions. To ensure there's supply, you still need to express at least every 3 hours. Eventually, I learn to nurse my boy while lying down and continue to sleep. I'm still doing this. My son is 16 mths now. Just make sure that your breast doesn't cover his nose.
