Fiance can't handle crying baby

We have an infant and my fiance is talking about a second baby already. But his ass always leaves the room when his baby cries because he can't handle it. He says when the baby gets older he's looking forward doing activities. And I say he should not avoid crying baby and only be there when their quiet and content.

Am I wrong here? Because he justifies it that he can't do anything for the baby since they always require mothers for their need like nursing
