Father PPD?

My husband and I have a 2 year old son and a 6 week old daughter. Our daughter is a complicated little thing and more often than not is fussing and crying. Over time my husband has become more and more frustrated with her and you can tell he doesn’t want to help take care of her because he just gets irritated by her not being soothed by him. Keep in mind we’ve done this before and he was very patient with our son, where I struggled with PPD and was the one getting frustrated easily. He told me today he thinks he’s experiencing some form of depression related to her but didn’t think men could have that problem. I explained to him that I’d think they could as the baby also alters their lives, not just the woman’s and encouraged him to contact his physician to possibly go back on his antidepressants he’s been on in the past. I’m just curious if anyone else’s husbands went through something similar?
