Your heart will literally stop when you see this video...

It’s a mother’s worst nightmare. You’re stepping off a train, your child is right behind you. You hear a blood-curdling scream and when you turn back to see what’s happening, your child is slipping out of your sight between the gap of the platform and the train, right on to the train tracks.

Watch this video from East Melbourne, Australia, posted by Romeo Masian on his Facebook page. And yes, it has a happy ending, but a very strong warning to all parents: never take your child’s safety for granted and always walk behind your child, especially while using public transport.
