A mother has shared a shocking image warning parents about a common playground mistake that saw her one-year-old daughter suffer a broken leg.

“This picture is the moment her leg was breaking. She’s still smiling… because it was happening at this exact moment,” Heather Clare wrote in a Facebook warning to all parents.

The mum was unaware of the risk she had taken until speaking to doctors later.

“When we went to the ER, the super empathetic doctor lectured me on how common this injury is,” she said.

“I had no idea. I thought everyone took their kids down the slide.

She is not only pleading with parents, but local councils around the world, to provide warnings about the dangers of sliding with young children.

“I strongly feel every playground should have a warning sign, but since I’ve never seen one (and we go to a lot of playgrounds),” she wrote.

“Don’t ever go down a slide with a baby on your lap. There is no SAFE way to go down a slide with your little one.
