Never stops feeding

Crystal • Married 10/12/14. Have an amazing son, born 11/27/15
Babe is 9 days old and cluster feeds like a mad man. Yesterday was 8 hours today I'm at 11 hours. He will take a 20-30 min break here and there, but then right back to boob. Went to a laceration consultant and was told he is latching and drinking great, gaining great and having lots of dirty diapers. She told me that it's "normal". Well this doesn't feel normal and i need some sleep. Any one going through this? Any insight?
