Son is not latching

Kelsey

My son is three weeks old, and I am a first time mom. He has been having a hard time with consistently latching and he gets himself worked up and starts crying, then he really won’t latch. What am I doing wrong? What can I do to make him want to nurse/latch? Is all hope lost with me being able to breastfeed? I have even tried pumping for him and I get very little out when I pump.
