Dear Kevin and Sarah,
My brother and sister-in-law recently adopted a child. For the past few weeks, my sister-in-law has been saying she has post-partum depression. I don’t have kids of my own, but I didn’t think having post-partum was possible unless you actually gave birth to a child. I know both you and Sarah have kids, so I wanted to see what you thought and if there’s anything I should tell my sister.
