A young mum was gutted after buying her son 'washable' crayons so he could draw on the walls while he was in the bath - as they refused to come off afterwards.
Cait Regan took to TikTok to share her news with other parents, as she didn't want them to find themselves in the same situation she was in.
In the short clip, she showed the walls around her bathtub - and the white tiles are covered in colourful scrawls from the edge of the bath to well above head height.
