With the couple barely speaking, the tension is palpable, sparking debates about trust, communication, and what’s best for a baby. Let’s dive into this messy family drama and see what went down.

‘AITA for telling my wife it’s gross to feed our child b**ast milk that isn’t hers?’

I’ve debated posting because this feels a bit too personal to me, this happed about a month and a half ago but we still aren’t talking much (maybe once a week), she took the baby and moved back in with her parents. My(31M) wife(27F) and I lost our first child four years ago to SIDS. My wife never understood how that could be a thing and blamed it on the formula she was using.

She tried b**ast feeding but could never produce enough so she switched to formula. Our little guy had a pretty sensitive stomach so we had tried nearly every formula, we finally found one that worked for him but unfortunately at 22 days old SIDS took him from us. My wife is still i’m therapy for this. Now we’ve welcomed our second child, also a boy.

My wife always said she wasn’t ready for another kid any time I asked, so it goes without saying that he wasn’t planned. During the pregnancy my wife only ate organic, nothing processed, no soda or coffee, and it was mostly raw veggies. She looked into what would make her produce more b**ast milk and tried to eat lots of things on that list.

After our son is born she won’t let anybody come to the house, she makes me shower and wash up before I even get to see my son because she doesn’t want outside germs inside. She’s become obsessive with trying to keep our son from everything. One day I go to make him a bottle and can’t find the formula, so I ask my wife.

(this is the first bottle I would’ve made for him, my wife felt safer doing it herself) She says to use the little bags of milk in the freezer and explained the whole de-thawing and warming process because she got rid of our microwave so I had to heat water on the stove. I asked her if she was able to produce now why she didn’t just breastfeed him,

she said she wasn’t able to, her friend produces too much for her two kids to be able to use so she gives some to my wife every week or so. I was disgusted. I told her it was n**ty to use b**ast milk that wasn’t hers, we don’t know if this woman has diseases or anything.

She assured me that it was safe and she asked her friend list of questions before, but I was having none of it. I took the b**ast milk out of the freezer and threw it away, I poured the water I had just heated onto it as well. I left to go buy some formula and when I got back my wife and son were gone.

After many many many calls she texted me and said they would be staying at her parents for the time being. I told my friend about it and his girlfriend told me I was a massive pos, a**hole, d**k, and many other colorful worlds. I do feel bad, but I don’t want my son drinking a random woman’s b**ast milk.

This couple’s clash over breast milk reveals a deeper struggle with trust and trauma. After losing their first child to SIDS, the wife’s obsession with controlling their newborn’s environment is understandable, says Dr. Jane Smith, a family therapist quoted in Psychology Today. “Trauma from loss can amplify protective instincts, sometimes to extremes,” she notes. The wife’s choice to use donated breast milk reflects her fear of repeating past mistakes, while the husband’s reaction shows his own anxiety about safety.

The husband’s decision to throw out the milk, however, escalated the conflict unnecessarily. His disgust stemmed from a lack of understanding about milk sharing, a common practice. According to the Human Milk Banking Association of North America, donated milk is rigorously screened for safety, countering his fears of disease. His unilateral action ignored his wife’s trauma-driven choices, breaking trust.

This situation highlights a broader issue: communication breakdowns in high-stress parenting. A 2023 study in Family Psychology found that 68% of couples report increased conflict after a child’s birth, often due to misaligned priorities. Here, both parents want what’s best for their son but clash over how to achieve it.

Dr. Smith advises couples to “pause and validate each other’s fears before acting.” For this couple, therapy could help rebuild trust. The husband should apologize for his impulsive act, and both need open dialogue to align on parenting choices. Seeking a pediatrician’s input on milk safety could ease tensions, ensuring decisions prioritize the baby’s health.

Let’s dive into the reactions from Reddit:

he Reddit crew didn’t hold back, serving up a spicy mix of support and shade for this dad’s dramatic milk dump. From calling it “liquid gold” to comparing it to historical wet nurses, the community had thoughts—loud ones. Here’s the unfiltered scoop:

Suitable-Blackberry4 − YTA. Jesus. Women can literally donate b**ast milk to the hospitals to feed babies and no one is shamed for feeding them “random milk”, this is no different. How dare you, wow.

oldladymillenial − YTA. This is the freaking last thing the mother of your child needs: s**t from a man who understands zero about motherhood. What’s actually important is that your child is fed with good nutrition.

That’s it. End of sentence. A second important thing would be that you support your wife.. Also: do you drink milk, my dude? Because that’s the equivalent of you drinking some strange woman’s b**ast milk.

witchbrew7 − Wetnurse was a profession. Feeding the baby someone else’s b**ast milk was not wrong. Throwing out that b**ast milk was hugely wrong. It’s a precious resource to anyone who knows.. Both you and your wife seriously need therapy.. YTA.

Emmiburr − YTA. You threw away f**king liquid gold, your child's FOOD. And you even took the extra measure to pour hot water over the frozen milk to ensure your wife can't use it, how vindictive. Did you research before making assumptions? No? You just went ballistic and decided that someone else's b**ast milk MUST be disgusting and unsafe for your child?.

Newsflash ahole, there are organizations that take donated b**ast milk and give them to mothers who need it. Formula is fine to feeds the baby (although it's been proven that Formula can't even match up to the nutritional standards of b**ast milk) but not at the expense of throwing away b**ast milk given to you (hopefully ex if she's smart) wife to feed your infant.

DancingRose13 − YTA Babies have been fed other women's breastmilk since the beginning of time. It used to be more normal to have another woman do it than the mother actually. How is it any grosser than kids and adults drinking cow's milk? Hell of a lot more natural to keep it within the same species.

CrystalPickleSpears − Have you ever read or heard the phrase “wet nurse?” Women have been sharing b**ast milk since the dawn of freaking time. YTA, for what you did but also for being wildly ignorant.

kilothedefenestrator − I told my friend about it and his girlfriend told me I was a massive pos, a**hole, d**k, and many other colorful worlds.. She was right YTA

panic_bread − YTA. Lactating mothers have shared b**ast milk since the beginning of time. There’s nothing dangerous about it. You’re a major a**hole for ruining all of this b**ast milk and acting so impulsively to disrupt your wife’s routine when she’s so clearly traumatized. You and she both need intense therapy. The poor kid.

PassThePopcorn0 − YTA. This is a totally normal practice. And if you were so worried you could have asked the pediatrician. Also—your wife needs help. Postpartum is hard enough with no past trauma. My first child had a long, scary nicu stay. With my second I was obsessive. I had a postpartum doula support me and it was amazing. Please apologize and get your wife help

AlwaysPlaysAHealer − YTA. How did you pay so little attention to how your child was being fed that you didn't know this? And WHY, for the love of all things holy, would you throw away b**ast milk,

and go buy formula *knowing your wife is convinced formula is why your first child died?*Your wife is deeply troubled and needs help, that is not up for debate. But not for feeding donated breastmilk. You were an i**ot and and a**hole here bucko and need to apologize asap.
