AITA for encouraging my daughter to body-shame the girl who is bullying her?

A 42-year-old dad signs his 10-year-old daughter Lucy up for a swim club. She’s small, slim, but a strong swimmer, placed in a high-ability lane with teenagers. Three weeks in, 14-year-old Z returns after a broken arm—tall, heavy, confident, and mean. Z starts targeting Lucy with nonstop taunts about her size: “You’re so skinny and insignificant, like a little stick. I could snap you in half or flick you away.”

Lucy comes home in tears, begs her dad not to tell anyone because it’ll only get worse. Reluctantly, he agrees—but shares how he handled bullies as a kid: hit back with something just as personal so they think twice. He stresses it’s only in response to an attack, never unprovoked. He suggests if Z says she could flick Lucy away, Lucy could reply, “Yeah, probably. But if I wanted to move you, I’d need a crane because you’re so big and fat.” Lucy laughs and says she might try it. Next practice? Z storms out of the pool crying. Her mom confronts the dad, furious about the “body-shaming.” Now he’s wondering if teaching his daughter to clap back made him the asshole.

‘AITA for encouraging my daughter to body-shame the girl who is bullying her?’

Everything starts when Lucy joins the swim club and meets Z—a bigger, bolder girl who wastes no time:

After two weeks of torment, Lucy finally breaks down and tells her dad:

Lucy pleads with her dad not to get involved, terrified it’ll escalate. He agrees but shares a personal lesson:

The very next session, things explode:

Later, he clarifies the size exaggeration in an edit:

This case forces a tough question: is teaching a child to fight back with body-shaming ever the right move? Z was clearly the aggressor—using age, size, and cruel words to intimidate Lucy. The taunts about snapping her in half or flicking her away were genuinely threatening. Lucy suffered in silence, afraid adult intervention would backfire—classic bully victim behavior.

The dad chose to equip his daughter with a verbal comeback, believing it would deter further attacks. It worked in the moment—Z stormed out crying—but the method carries heavy risks: it normalizes body-shaming as a defense tool, which can backfire during puberty when both girls will be hyper-sensitive about their bodies. It also teaches that cruelty is okay if you’re the one who was hurt first.

Child psychologist Dr. Barbara Greenberg emphasizes: “Responding to bullying with personal insults, even defensively, reinforces that judging and attacking appearance is acceptable. At this vulnerable age, girls face intense pressure about looks. The healthier path is teaching clear boundary-setting (‘I won’t accept comments about my body’), reporting to trusted adults, and building internal confidence instead of tearing others down.”

A stronger approach: document incidents (dates, exact words), speak privately to the swim coach first (they have authority over pool behavior), then escalate to parents or club management if needed. Real-world tip for parents: always back your child, but guide them toward mature conflict resolution—setting limits, seeking adult help, and protecting self-worth without harming others. Even if Z backed off this time, the long-term lesson about respect and resilience matters far more.

Here’s the comments of Reddit users:

The internet split hard, but most sided with the dad (NTA), arguing protecting your kid trumps politeness to a bully:

Most readers backed the “fight back” strategy, sharing personal stories of how clapping back finally stopped their tormentors:

A smaller group called him out, saying adults should model better behavior:

This story highlights how protecting your child from bullying can lead to messy, emotional decisions—especially when body-shaming is involved. Most agree Z needed to be stopped, but teaching a comeback that attacks appearance still worries people about the bigger message it sends to both girls.
