Eating too frequently?

Sara
My EBF 6 week old wants to eat practically every hour and only sleeps max 3 hours at a time at night. He's always been like this, so I don't think it's a cluster feeding/growth spurt thing. Is this normal? Should I be pushing him to wait longer between feedings? I'm making plenty of milk I think because I pump 3-6 oz per session in the morning. I go back to work soon and also would like to sleep for longer stretches! Is this normal? Any suggestions? Help?!?!
