1 week old feeding constantly help!

My bubs is one week old and for the first 5 days couldn't latch so we pumped. We are now latched and feeding well but he won't have a break he is feeding constantly I feed him take him off put him down and he cries until I put him back on. When I pump he gets between 100 to 130 mls but still isn't full for long maybe 2 hours if I'm lucky. Am I doing something wrong? I don't even have time to eat
