People can be forgetful, and you may not want to admit it, but most of us have forgotten our child in the car at least once.
It happens ladies, no judgement here... however it can be pretty dangerous.
Thankfully, nine-year-old Sophie Rapson has invented something that will stop this from ever happening to you again, and it will only cost you €10.
According to Sophie's mum, the youngster is not selling her invention, but "she doesn’t mind if you copy her design".
Don't mind if we do...
Sophie’s invention is made of just two things: velcro loops and stretchy cord.
So simple, yet could save so many lives! Check out the video, and see how this handy contraption works.
