Taking to Twitter, Phoebe Bartlett, shared that her mother had discovered her 3-year-old brother's shameful secret.
Speaking to Buzzfeed News, Bartlett explained her mother stumbled upon a chest of drawers that the toddler was using as a toilet.
She captioned a photo of the youngster, 'Mum has just found a draw full off piss that my 3 year old brother has been pissing in and he blamed the dog HAHA!!!'
'What happened was mum could smell wee in her room for about a week, but couldn’t find a patch from the dog, so she asked my brother if the wee was in her room,' she told Buzzfeed.
'He must have been doing it while he’s in his room watching his tablet, which is also on the drawer, and can’t be bothered to go to the toilet, so he opened the drawer and was peeing in there.'
Other mothers were quick to react to the hilarious tweet - sharing their own children's toilet training stories!
