This is the remarkable moment a parent is caught on camera helping her toddler grafitti a plane's tray tables.

The brazen moment was posted on social media by an Instagram account called 'Passenger Shaming' and showed a parent and child on an unspecified flight drawing all over the seats in front of them.

'Not only are tray tables for changing s****y diapers on, now you can help your kids draw all over them! It's only a $100M aircraft,' the Passenger Shaming caption read.

The parent was filmed guiding their child's hand as they drew all over the back of the seat in front

As the clip begins, the cameraman shows his own tray table which has been covered in crayon markings.

But as he pans across with the camera it's possible to make out a load more graffiti on the seat-back next to him.

The child can be seen sitting on its' parents lap as it carries out the act of vandalism.

At one point the adult even guides the child's hand as it draws all over the seat in front.

Footage of the incident, which was initially circulated on Reddit, provoked outrage on Instagram where users blasted the adult in the video for their 'horrible parenting'.

'What bugs me is the “corrective” parenting to put the pencil back in the “draw” area,' one person wrote.

Another said: 'This p****d me off more than the rest of the video. God forbid that child draws in a non parent approved area.'

'Even if they're intending to break out the goo-gone wipes and clean it up themselves, this is horrible parenting,' one person commented, 'Children need to learn young about how to respect things they don't own.'

The incident appears to have taken place on a Lufthansa Airbus A320, although it is not known where the plane had come from or was heading.
