Families are weird. Some expect you to bring a side dish to dinner. Some expect you to help with the dishes. And then there are families like OP’s, where someone casually assumes you’re on-call as their personal diaper intern.
OP has been married for more than a decade, has several kids, and has done his fair share of diapers, late-night vomit emergencies, and car-seat wrestling matches worthy of the Olympics. But unlike his sister-in-law, he does not outsource parenting tasks to whoever is within a five-foot radius.
Still, this isn’t the first time SIL has acted like other people are the background staff in the movie of her life. She asks OP’s family to stock her toddler’s special snacks, asks people to “watch the baby” while she scrolls TikTok, and seems to think everyone automatically signed up for her parenting co-op.

Here’s The Original Post:
















Dinner at MIL’s house was supposed to be calm. A normal family meal: food, chatter, and hopefully no arguments about politics or who forgot to bring dessert.
But halfway through dinner, the baby has a situation – a poopy diaper. No big deal, right? Babies do that. Constantly.
But instead of either parent getting up, SIL looks at OP with the sweetest, most weaponized Disney-princess voice and asks:
“Uncle ___, can you change the diaper?”
OP is stunned. This isn’t babysitting night. Both parents are right there. One is even scrolling on their phone, blissfully unbothered. OP decides it’s time for something revolutionary: a boundary.
He responds calmly:
“No, I’m sorry, I don’t do that.”
SIL’s eyes widen. You’d think he said he doesn’t believe in gravity.
“You… don’t do diapers??”
OP clarifies that he doesn’t change other people’s kids’ diapers when their own parents are present. If he’s babysitting alone, sure. But he’s not the designated diaper dad. SIL immediately shifts into wounded mode:
“Well… I feel selfish.”
OP tries to ease the tension with a smile and a soft reply:
“Not trying to make you feel any way, just sharing a boundary.”
But the table goes silent. SIL gets up, changes the diaper, and the awkward energy thickens like gravy. After dinner, OP’s wife scolds him for making SIL feel bad. According to her, he could’ve “just changed it.”
This is where OP draws the line. He’s raised three kids. He’s changed more diapers than he can count.
But he’s never asked another adult to do it for him when he was standing right there with two functioning hands. He doesn’t want to become the honorary third parent by default.
It’s a reasonable stance. In fact, according to a 2023 Pew Research study, 62% of parents report feeling overwhelmed because they lack support – yet only 18% admit they sometimes expect too much from family members.
SIL appears to be living squarely in that 18% – and pretending it’s everyone else’s normal.
The deeper issue is that OP isn’t refusing to help because he’s cruel or lazy. He’s refusing because saying “yes” once guarantees he’ll be asked again and again. That’s how boundaries disappear – quietly, under layers of baby wipes.
Let’s dive into the reactions from Reddit:
Many commenters say OP is NTA, noting that the SIL tried to guilt-trip and manipulate by pushing a boundary after OP said no.







Reddit users didn’t hold back, and many were quick to side with OP while pointing out the bigger issue within the household dynamics.

Other redditors swarmed the post with firm opinions, and many argued that the diaper wasn’t the real issue at all.






OP didn’t refuse out of spite. He refused because saying yes would make him the default diaper guy for years. SIL may not love hearing “no,” but adulthood is full of inconvenient truths – like the reality that diapers fall squarely into the “parenting responsibilities” category.
OP drew a healthy boundary, stayed calm, and refused to let guilt push him into a role he never signed up for. And honestly? More people could stand to practice that skill.
