Will they never learn? Another set of worrying pictures show how parents can get it so, so wrong.
Usually, parents will do anything to keep their precious children out of harm's way.
Whether it is preventing them from watching violent scenes on TV, or from riding on a white-knuckle ride at a theme park, they do their best to protect them from life's dangers.
But, as these shocking pictures show, this rule does not apply to all parents.
Disturbing: This father is pictured reading the adult magazine Playboy with his young child.
Worrying: A mother puts her daughter in danger by walking across thin ice.
Not suitable: This man, centre right, is clearly enjoying watching a woman dancing in a bikini. However, his daughter looks slightly less impressed.
Dangerous: Windsurfing is a sport which many adults would be terrified of attempting. But his dad decided to strap his baby to his chest when he went out to sea.
Trapped: This child cannot be comfortable riding at the back of her (rather large) mum.
Mother's and father's have been pictured exposing their children to dangerous situations and sexual images.
In one picture, a father can be seen reading the adult magazine Playboy with his young child while, in another, a young girl sleeps at the feet of her mother who is drinking at a bar.
Unorthodox: This father takes a photograph with his child resting between his legs.
Unorthodox: The woman thought it would be a good idea to pose with a child hanging upside down.
In harm's way: Many children enjoy eating cake mix.....but most parents wouldn't allow them to put a plugged-in food mixer in their mouth.
Fall: This man looks very happy with himself on a swing, but the child behind him who has been knocked over by him will be less impressed.
Foolish: It might have been wiser for this mum to place her baby on the pavement rather than in the road.
Unsafe: This father travels on a rickety-looking bike with his two children attached to the back... and neither are wearing helmets.
What is she thinking? This mother continues with her shopping while her child puts a plastic bag over her head.
Dozing: While this girl's mother enjoys a drink at the bar, her daughter is passed out asleep at her feet.
Painful: With this young boy clearly in pain after being trapped underneath a toy truck, his parent thought it would be a good idea to take a picture.
Dressed-up: Nothing about this picture is right, particularly as a young child is involved.
Not right: This mother could perhaps have found a better way to put her child back in his buggy.
Confused: This little baby isn't sure what to make of the toy bullet which has just been fired at his head.
Chilling out: While his parents shop, this child is left relaxing in a trolley in front of a giant TV screen.
