A mum was left fuming after her 10-year-old daughter's stepmum let her watch the controversial Netflix show Squid Game.

The mum was horrified after finding out from her daughter's maths tutor that she had sat and watched an episode of the graphic and violent cult hit.

The South Korean show is Netflix's most watched hit ever after pulling in 111m viewers worldwide and topping streaming charts in more than 80 countries.

The show features hundreds of desperate and debt-riddled contestants as they accept an invitation to compete in children's games for a tempting prize, but if they lose any of the games, they die and violent death.

However many schools have issued warnings to parents not to allow their children to watch the show, which is rated 15+, as a result of the graphic and disturbing scenes.

However some parents seem to be fine with their children viewing the show, as was the case with the stepmum in question.

She confessed on Reddit that she had let her stepdaughter watch it after she claimed to have already watched five episodes at her mother's house.

An unnamed woman from the US took to Reddit's Step Parents forum, to ask for some advice.

The step mum wrote: "My SD (10) was at our house last weekend and asked me if I wanted to watch Squid Game on Netflix. I saw it pop up on my own Netflix a few days prior but didn't read the description or anything like that.

"SD told me she had already watched five episodes but that she would watch from the beginning for me.

"So...I said, 'Sure!' and she and I watched episode one. Only one episode. SD even went on to finish the series on her own at her mom's house. Episode one was bloody and stuff, but I figured since she had already watched five episodes at home, it was ok with her mom. SD was not afraid of anything we watched. We even talked about how everything in movies is fake, special effects, etc...

"Well, apparently it wasn't ok with BM (birth mum). SD's math tutor mentioned that SD had mentioned Squid Game to her during their math session and BM was appalled when the math tutor (who doesn't have children) told her how inappropriate the show was for children.

"BM went off on SO, but turns out that SD had watched the first five episodes and the rest of the series on her mother's laptop. So...um...what?

"I've got a son, so I am a mom too and I understand we don't want our kids watching things with themes they don't understand, but unbeknownst to BM, SD WATCHED THE WHOLE SERIES AT HER MOM'S HOUSE, yet it's our fault?"

The parent added that she wasn't sure how to handle the situation.

"BM is a really good mom and not high conflict at all. We get along very well and I like her very much, but she has not talked to me about the Netflix show, only my SO (significant other).

"She wouldn't talk to me about it because she general does like any confrontation, so I guess we just proceed with business as usual, except now I will think twice the next time she asks me watch something with her!"

Dozens of people responded to the post, agreeing that the TV show was "highly inappropriate" for children.

One person said: "I'm a secondary teacher (11-16) and we've had to send emails out to parents asking them not to let their kids watch that show. A ridiculous amount of my 11 and 12-year-olds have been watching it too. It's not your fault your SD lied to you, as long as your SO made that clear to BM then business as usual seems like the right approach."

Another agreed: "Squid game is HIGHLY inappropriate for a kiddo that young even understanding all of the props. Honestly it sounds like SD kind of manipulated you not knowing she was watching it without clear approval from her BM. a clear boundary between what's appropriate should be set by all parties but I can understand why she'd be upset.

"She needs to take responsibility for the fact though that her 10-year-old is having so much unsupervised computer time that she could watch so much of it at her home. Each of you have some hand in it, including SD and her parents should have a direct conversation with her about what's appropriate and playing households against each other."
