The most common cause is a very high temperature (fever), due to the young child’s brain being less tolerant of variations in body temperature so that a fit (febrile convulsions) results. These fits should not be confused with temper tantrums.Young children and infants can suffer from fits (convulsions) for a number of reasons
That the child has a fever.
That the child is very hot, has flushed skin and may be sweating.
That the child is fitting: arched back, muscles twitching, jerking movements.
You may notice
The eyes rolling upward.
The child’s face may be blue if the breath is held.
Dribbling/drooling at the mouth.
Remove any covering and clothes.
Sponge the child with luke warm water. Do this by starting at the head and regularly refresh the water in the sponge.
Prevent the child from hurting him/herself if the fit continues; place soft padding such as pillows around the child.
Do not try to restrain the child by force.
Once the fit stops, continue to cool the child.
Call for an ambulance.
Do not overcool the child once the fit has finished, cover the child with a light covering, e.g. a sheet.
