Little Tianna Lewis McHugh is the girl who cannot cry - because it could kill her.
The two-year-old has a rare condition which means tears could trigger a fatal fit.
Her parents, Ceri Lewis and Andy McHugh, face a daily battle to make sure she doesn't cry.
Tianna looks as though she's died when she has a terrifying Reflex Anoxic Seizure (RAS).
Her skin goes white, her body stiffens, her heart stops beating and she stops breathing.
Other children with the condition react to pain, fear or fright, but Tianna has a form so extreme that simply crying can trigger a fit.
She was diagnosed with the condition aged 18 months and has since survived 10 seizures.
