On Monday, Victoria Beckham posted a photo of her daughter, Harper Beckham, for her 5th birthday. In the image Beckham is kissing her daughter on the lips. Many commented their disapproval of the kiss, calling it “horrible,” “controversial” and “disgusting.”

Other parents came to her defense and posted similar photos to prove the act is acceptable between a parent and child.

I will always kiss my daughter on the lips no matter how old she is. #victoriabeckham #kissyourchildren

Others, including children that still kiss their parents on the lips, scolded those critics.
