Ever been stumped by your child’s sweet, innocent face as they try and pin a cheeky act on their sibling? One mum has discovered a brilliant way to tell if kids are telling the truth. And it’ so simple we wish we’d thought of it earlier.

The tip was posted in response to a TikTok asking mums to reveal the most useful lie they’ve ever told their kids. TikTok user Victoria then blew everyone’s mind when she detailed her simple tip.

“I told my children that when they lie, a star appears on their forehead, that only a grown-up can see,” she explained. “So anytime they’re lying to me, they cover their forehead.”

Genius! The video has had more than 20 million views from thankful parents. Other mums then took to the comments to share their useful parenting lies.

“Told my son that when the ice cream truck played music it meant they were out of ice cream.”

“My mum told me when I lie my ears turn pink so I would run around holding my ears.”

“We can’t be awake until the sun is awake.”

“My mum used to tell me if I ate my boogers I would turn into a tree. She said the tree outside was my brother.”

“My mum told me when I lie I grow a dog tail so I’d always look behind me.”

So, what’s the most useful lie you’ve ever told your kids?

  • I love that idea. My kids are too old for that now but if I tell a lie my cheeks so bright red


  • I don’t think it would work for very long but definitely cute that they cover their forehead.


  • Classic. What a great idea. Must be hard for Mum to keep a straight face when she sees the kids covering their foreheads.


  • That lie is genius! Definitely trying it!


  • Haha, that’s gold!


  • I have no problem with this!!! Will try it on my twins tonight!
    bla bla bla….as for the lying to kids what about trust line: …yadda yadda….erm, santa, tooth fairy?!


  • That is such a clever idea ! I wish I could use it on my teenagers.


  • How funny. And genius


  • Haha, these are all so funny. I can just tell when my son is lying. It’s a look on his face… and if I stare at him long enough questioning his lie, he breaks!


  • I some times telling them wrong time in the morning to wake them up early.


  • I’m sure I have, but I can’t for the life of me think of one! Santa, Easter bunny, tooth fairy etc be the biggest lies


  • Haha thats too adorable covering their forehead. My daughter does a cheeky grin and i just know when she lies.


  • If you know your kids, you’ll know when they’re lieing. I pick almost every time my step kids try and lie to me. God I was a kid once. Of id lie about it to a parent to cover my backside, then so will they. They don’t get much past me at all.


  • Yeah doesn’t this contradict what you are trying to tech your child not to do? I just try to talk to my kids about why they shouldn’t lie.


  • Funny! We used to be told things like that when we were kids but when we were old enough to understand that it wasn’t exactly true we didn’t think for a minute that our parents were lying.
