Boyfriend and baby

So me and my bf had a baby a month ago. And it’s awesome but my bf doesn’t do much. He loves her so much but doesn’t ever want to really help or hold her for more than 10 minutes. If I try to say something about it he gets really mad even if I say it nicely. He always just says she’s hungry and passes her back to me. Idk how to get him to be with her more and help me more
