Short nursing times?

Miranda

My 1 week old only nurses for 5-6 minutes on one side only and then doesnt want anymore for another 2 hours. I have a pretty heavy stream that he needs to release and swallow the milk stored in his cheeks about 10 seconds after starting and my stream has caused him to cough too. Just wondering if the heavier flow is causing the shorter feedings and he is getting enough to eat or if I should be concerned about his eating..
