Baby's feeding.

So I know I should probably be counting my blessings but I can't but ask if this is happening to anyone else's baby. My DD who is 21/2 weeks old will cluster feed about 8-10 ounces between the hours of 6-8 (or 15-20 minutes nursing) then sleep until around 130-300 wake up, drink maybe 3 oz and go right back to sleep until around 6 or 7. Is that normal for a two weeks old ? Def not complaining just not sure if it was different. This is my first baby.
