AITA for correctly guessing my friend’s baby’s sex?

A festive gender reveal party, balloons popping with blue confetti, should be all cheers and cake. But for one couple, the drive home turned sour. When a man’s statistical guess about the baby’s sex proved right, his wife saw cold logic where she wanted warm support, leaving their car ride steeped in silence.

This lighthearted spat over a baby’s sex reveal tickles with relatability. When does a factual answer clash with emotional hopes, especially in the glow of a friend’s big moment?

‘AITA for correctly guessing my friend’s baby’s sex?’

On the weekend my wife (38f) and I (39m) went to our friend's 'gender reveal'. For background information, our friend already has 2 boys, and she told my wife that she is hoping for a girl this time. In the car on the way there, my wife asked me what gender I thought the baby would be.

I said that given that the s** ratio at birth is about 105 boys for every 100 girls, that my guess is that this child would be a boy. My wife said that given our friends had 2 boys already, that surely there would be more chance of a girl this time.

I replied that the 2 boys were not relevant to the s** of the child our friends were expecting, and that there was still about a 51% chance this child would be a boy. At the 'gender reveal', it was announced that this child would also be a boy.

Although our friend tried to appear happy at the party, it was clear that she was disappointed that this child would not be a girl. My wife also appeared to be disappointed as well. On the drive back home, my wife got angry with me, and said that I 'could have been more supportive'

and that I 'shouldn't have been so mathematical' with my guess about the baby's s**. I told her that my response was perfectly reasonable to the questions she asked me. She didn't like that and stayed quiet for the rest of the drive home.. So Reddit, AITA?

Gender reveals are less about science and more about shared excitement, but this couple’s clash shows how logic and emotion can misfire. The man’s stats-based guess—51% chance of a boy—was factually sound but missed his wife’s unspoken wish for hopeful camaraderie. Her anger suggests she wanted a partner in optimism, not a probability lecture.

Relationship expert Dr. John Gottman notes, “Small moments of connection build trust.” Missteps like this, where 60% of couples misread emotional cues per studies, can sting. The wife’s disappointment, tied to her friend’s hopes, wasn’t about the baby’s sex but the man’s tone.

This highlights broader communication gaps. Dr. Gottman advises, “Listen for the feeling, not just the words.” The man could acknowledge his wife’s perspective and share hopes next time.

Here’s the input from the Reddit crowd:

Reddit jumped on this gender reveal drama like confetti at a party. Here’s the crowd’s colorful take:

hatterson − When your wife said you 'could have been more supportive' did she mean supportive of her and her guessing game or more supportive of the mom to be who is disappointed in her child's chromosomes?. Either way, NTA. You answered the question you were asked in a normal way.

Edit: You were effectively asked whether you think a coin flip will land on heads or tails and answered that statistically it was slightly more likely to land heads. Your wife said because it had been heads twice before it must have a higher heads chance now and you confirmed that it doesn't work that way*

*Technically them having two boys already would very slightly increase the chances their next child is also a boy since there are some genetic factors that can lead some people to have more boys and some to have more girls and them having two boys already very slightly increases the chances they're in the 'more boys' group, but realistically the conditional change in probability after only 2 boys isn't meaningful.

Arorua_Mendes − NTA. You answered the damn question you were asked. Your wife wanted you to participate in magical thinking not give an honest answer. You gave a factual answer and didn't announce it at the party or rain on anyone's parade.

You simply answered your wife's direct question with your genuine thought process. Your prediction didn't cause the baby's s** for f**k's sake it just acknowledged reality. The problem isn't your mathematics it's that people sometimes want comfort more than truth. This isn't on you it's just misdirected emotion.

CrimsonKnight_004 − NTA Eh? No matter what you said, it wouldn’t have changed the s** of the baby. I have no idea what “being supportive” would’ve done to help the situation. You said this to your wife, not the friend. You weren’t rubbing anything in her face or sh*tting on what *she* was hoping for. You had a private conversation with your wife.

I guess your wife is just lashing out and taking out the disappointment on you? So I wouldn’t take it personally, but once a little time has passed and she can get some perspective on this, I’d revisit this with her and ask why she felt the need to take this out on you.

[Reddit User] − Doss your wife get angry when you guess a coin toss right? This is ridiculous! NTA. As for being 'supportive', you didn't tell the expecting mother about your guess, so it wasn't like you crushed her hopes or anything like that.

Also, what's so bad about having a boy? Some people create a lot of expectations on a child's s**, but honestly they should repress that. Like, how would you feel if you knew your parent was disappointed with your birth s**?

Marzi_R0s3 − Just to add that actually the s** of the previous kids is relevant, it is not a 50% chance to get a boy or a girl, some men are more likely to get boys and some men are more likely to get girls and will have odds of, for instance, 70%-30% depending of their sperm, and if someone already has many boys it is an indicator that the man probably has a higher chance to produce boys and statically another boy is more likely.

KrofftSurvivor − NTA. Your wife asked you what you thought, you told her.. She asked you why, you told her.. People need to stop asking questions they don't want the answers to.

Snurgisdr − Sounds like she asked ‘what do you predict’, but what she really meant was ‘what do you hope it will be’. NTA for not reading her mind.

sarahkazz − NTA. Not gonna lie, this sounds like a proxy issue for something else. Your wife’s response was ridiculous, but it may not be a bad idea to check in on her and make sure something else isn’t a thorn in her side that caused her to react this strongly to this.

alixanjou − NTA but people are being too hard on your wife. Form her reaction it seems like maybe you’re “Mr logic man” and what she wanted in that moment was for her partner to participate in her optimistic hope. It would’ve been better if she asked you “what do you *hope* it is?”

And then you two could’ve bonded. Or maybe you don’t really care, which is fine, but I can see why she thinks that dulls the sparkle a little. Sounds like she loves this friend and is invested and your cold mathematical probability answer just didn’t scratch the itch of what she was looking for.

I often think of what these interactions with my female friends would be like, and I think it’s a great reminder of how differently men and women can think about these things.. “Omg what do you think the baby will be?”. “Well maybe a boy but I hope it’s a girl!”.

“Come on, they already have 2 boys!”. “I know it’d be nice to have a girl” OR “and 3 would be crazy!” I truly can’t think of a woman in my life who wouldn’t respond like this and would choose to go “well that doesn’t really increase the chances.” And share nothing about their own opinion.

Fun-Independence-282 − NTA. It is quite literally not that deep.

These hot takes are lively, but do they catch the full vibe? Was the wife overreacting, or was the man tone-deaf?

The man’s logical prediction clashed with his wife’s emotional hopes, raising questions about support versus honesty. What would you do if your factual answer upset a loved one’s expectations?
