What happens when a child has convulsions Convulsions due to fever usually only last a minute or two. When your child has a fit, she will probably lose consciousness and begin to twitch uncontrollably. She will clamp her jaws shut tightly and breathe heavily. Her eyes will roll back into her head and she will froth at the mouth. She may even become incontinent.
Children usually fall asleep after the convulsions have passed.
What do I do when my child has a fit Do not panic and rush off to call for help. It is more important not to leave your child alone as she may inhale her vomit if she is sick. To prevent this from happening, place her on her stomach with her head to one side. Do not try to restrain her in any way. Try to keep her away from objects and furniture against which she may injure herself.
