The photo of a toddler who was left by his mother in a parking spot for 20 minutes has gone viral.

The toddler was seen by a passerby, Winn Tan, in a car park in Kuala Lumpur who subsequently posted a photo of the child on Facebook.

According to The Star Online, the mother returned to the parking spot after 20 minutes.

Tan reportedly thought the boy was lost but after asking him what he was doing there, the child revealed that his mother had instructed him to sit and wait on the parking spot.
