Anger and PPD

Alicia

I know a lot of people are mainly depressed or have baby blues but does anyone get angry? Would that be a sign of ppd? I really don't know why but sometimes I get very angry when I can't get my baby to stop crying or figure out why he's crying. I've learned how to manage it now but I feel like a horrible mom because he's so tiny and innocent, there's no reason to be angry with him.
