Having a baby is supposed to be a joyous occasion, and it often is. But just like with everything involving human behavior, pregnancy comes with unwritten rules of etiquette. So when someone breaks one, you know there’s gonna be an argument over who’s wrong, who’s right, and even whether the rule is legit in the first place.

One of these rules is, Mom gets to hold the baby first. Makes sense, right? I don’t think I need to explain why that is.

But that’s not how it went down for one UK-based mother, who anonymously posted her story on Mumsnet, a parenting and pregnancy-centric website. During her delivery, the anonymous mom had undergone a C-section and was still being sewn up when her mother-in-law went into the operating room and was the first family member to hold the baby. Here’s the full post.

(Side note, they use abbreviations like “DH” for “Dear Husband” and “DD” for “dear daughter,” etc.)

OK then!

There are a few key pieces of information to consider:

1. This was an emergency C-section and a traumatic birth.
2. Anonymous Mom had said to her husband before the delivery that she didn’t want any family members at the hospital.
3. Anonymous Dad didn’t actually ask his mother to come to the hospital; he was stressed and called for support, and she took the initiative to show up on her own. (She’s a doctor who works at the hospital, but not the obstetrics department.)
4. In a comment on her post, Anonymous Mom characterizes her mother-in-law as a “dominating and controlling” person who uses her status as a doctor to bend the rules.
5. And finally, while Anonymous Mother-In-Law was in the delivery room, she overheard a midwife discussing Anonymous Mom’s “sensitive medical information.”

Many people on Mumsnet took Anonymous Mom’s side:

But, some put the onus more on the husband than the mother-in-law, saying he should have been more aware when making the phone call.
