Lorna Howes was busy at work when her son rang her in despair about his 12-year-old sister Katelinn, who was fitting in their family living room.
The mum-of-three could "hear the horror in his voice" as he described the moment her body began to shake, her eyes rolled backwards and her mouth frothed.
Lorna, 46, raced home and arrived shortly before an ambulance, to find her daughter recovering on the sofa, having never experienced a seizure before.
