Should you let your children swear at home? A Kiwi doctor weighs in

Most of us feel guilty about dropping an F-bomb around kids.

But when mother-of-four Casara proudly announced her profanity-positive parenting style permitting her kids to swear, the internet exploded.

"They know when they can swear, how they can swear and who they can swear around - and they're allowed to swear," she explained on TikTok. "If you think the worst thing your child can do is swear, then you have another thing coming."

However, when The Project asked people on the streets of Auckland what they thought about the idea, a vast majority said, "Yeah, nah".

We're not the only country where most people feel cursing and kids don't mix. A British study found just one in five parents are comfortable swearing in front of those under 16.

"I think there's a big difference between stealing and swearing. The reality is that swearing is probably one of those things we're all slightly hypocritical on."

The worst response may be to overreact.

"Coming down like a tonne of bricks doesn't tend to work, because we are inadvertently reinforcing the behaviour we don't want," Dr MacDonald told The Project. "I think what does work is to actually explain to them why it's not a good idea... because [if they swear at home] there's a higher chance it will slip out in the world."

And if you are looking to curtail your kids' swearing, you might want to first look at yourself.

"We have to address our own behaviour. It's really important that we look at how we talk to each other as adults," he told The Project. "So if you're concerned about your kids' swearing getting out of line, it's a good idea to check your own swearing first."
