Postpartum depression in dad?

We just had our little girl in August 23rd and mentally I feel great. I’m very happy and floating on cloud nine, but I’ve noticed that my husband is not doing very well at all. Can dads get depressed after baby is born. He’s been extremely helpful and supportive of me and takes care of our daughter amazingly. But his demeanor is very very different. And right now he’s in the bathroom talking to his mom and I can hear him telling her about how depressed he is and in how dark of a place he’s in right now and I don’t know how to help. He’s trying to take as much off of me that he can and I think he’s running himself into the ground. I love this man more then anything and hearing him talk about how much he’s hurting makes me feel horrible. I just wish I could do something and I’m at a loss of what to do.
