Hundreds of parents have recorded videos of the moment they pretend to bump their babies' heads for a new viral trend.
The clips, which were filmed in China, has children crying over injuries that haven't actually happened.
In the videos, the parents can be seen holding their child close to a door or window before tapping it with their free hand.
After making the thumping sound the parents quickly rub their baby’s head to “comfort” them.
In the clips the parents can be heard saying: “Did you hit your head? Does it hurt? It’s ok, don’t cry,” as they try to sooth their kids.
The babies then burst into tears over their non-existent injuries.
The prank has received mixed reactions after it was posted on Reddit.
User mjolnir76 said: “This reinforces how strong the parental reaction is for kids.
“I can’t tell you how many times my kids took a small tumble and looked to ME for how to react. I didn’t freak out, so they didn’t freak out.”
Reddit user devetsil remembered his father doing something similar: “My dad used to do this to me when I was a toddler, but the reverse.
“Whenever I fell over he would laugh at me. And like an idiot baby, I assumed something funny must have occurred and would start laughing too.”
