A mum ‘waterboarded’ a baby – then posted the twisted content to Facebook.

Caitlin Alyse Hardy has been charged with child cruelty after the disgusting clip was posted on social media.

Each time the nine month-old tot cries out in distress yet laughter is heard in the background.

The footage was posted on Hardy’s Facebook profile, police say, and with a caption saying “Payback for waking me up all kind times of da night” followed by three laughing emojis.

Hardy, 33, was arrested by police in Sumter County, Florida, after the clip was shared on social media.
