Now parents are throwing their weight behind the fashion designer and taking to social media to show what they think about kissing their children.
More than 5,000 comments have been added to Beckham's Instagram post, with some users voicing their outrage, and others insisting that there is nothing sexual about a mother kissing her daughter.
The parents who saw nothing wrong with the gesture took it one step further and shared their own photos on social media.
Mothers and fathers alike are throwing their family photos into the debate, proving that they see nothing wrong with giving their children a friendly peck.
