“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.)
Having kids is both heart warming and rewarding and can also be heartbreaking. We had 3. No.1 was a real handful, today we do not communicate. The other 2 turned out just fine.
