A dream holiday ended in a parents' nightmare when three-year-old Imogen Roberts from Raunds in Northamptonshire woke up unable to use her legs.
Her parents thought she was just tired after recovering from a virus but she had been struck down with a condition called transverse myelitis.
Imogen now faces a long and painful battle to walk again.

Imogen was on a family holiday in Belgium when she caught a virus. She was taken to hospital by her mother Holly as a precaution.
Holly Roberts said: "She ran out of hospital singing and dancing, normal Imogen, went to bed fine and in the morning she just couldn't walk."
The virus had led to transverse myelitis, a rare neurological disorder caused by inflammation of the spinal cord.
Holly's trying to raise £10,000 to pay for intensive physiotherapy, hoping it'll give Imogen the best chance to walk again.
