Some awful, sad stories on here. Why are some people so vile and cruel to women who have just had a baby? 😢
I'd gone back to work when my first child was just 8 or 9 weeks old, (nearly 30 years ago...) About three or four weeks in, I was very tired and weary (on day 1 of a 2 day training course) as my baby had only slept three or four hours overnight.
One of the women on the course who was in her mid 20s, and single, with no children (from another branch, but still the same company - who I had only met once in the 2 years I had been there) said 'what's the matter with you? Why are you so tired?' I said 'oh sorry, my baby kept me up half the night and I'm a bit weary....'
She said 'well you didn't have to have it, nobody asked you to, no good bitching about it now. Go euthanize it if it's that bad!' 
I was genuinely glued to the spot with shock and horror at what she had said ... I made my excuse a minute or so later, and went into the toilets and just burst out into floods of tears. I couldn't believe that any person could say such a cruel, vile, sadistic thing.
I went back into the room and went to sit on the other side of it (away from her) and told the course leader that I didn't want to sit next to her as she had been quite nasty to me. She spent the next 2 hours that I was on that course laughing and giggling with three or four other women, and pointing at me. I was still wiping my tears at the desk for a few minutes.
I went back home and rang in sick the next day. I came back and told my manager what she had said and he said he would tell her manager. But all that happened was they said it was just 'banter' and I needed to grow a thicker skin! FGS!
I never saw the woman again. Thankfully. Absolutely fucking vile. Even 30 years later, it's still jars. (If I think about it. I mean, I very rarely think about it, but occasionally I do if someone chats about something similar.)
I left that workplace half a year later.
