OK, I’ve heard about “Post baby blues” and I don’t think this happens to women only. Not the same as a woman, but I know what kind of stress children can cause, none of it their fault, but I know I had to work harder, make more money, stay up at night when they were sick, worry if they weren’t eating enough, or maybe too much, etc. Having children changes your life instantly. But I think hormones come into play for women, probably making matters worse.
“I’ve heard about ‘Post baby blues’”
In the paragraph, it mentions the post-partum blues. It’s rather benign, and is the least severe of all the levels. The blues, PTSD, and psychosis supposedly are due to a chemical change in the woman — probably “hormones”, as you say.
What you mention must be true, too, considering the changes and stress in the home. It has to affect everyone. I can’t even imagine ... Never had kids; never wanted to. Didn’t want to take a chance after growing up in an abusive home, so I broke the cycle. Ditto for DH.
Maybe psychosis due to childbirth isn’t CO’s problem. Maybe there’s mental illness in her family. It would be interesting to know. (Or to “KNOW know” as she says.)
