Your child should be protected with 3 layers of clothing to prevent frostbite or hyperthermia. Cover ears, nose, and hands. Ibuprofen or acetaminophen are o.k. Check the label for proper dosage and expiration date. Take your child to the nearest pediatric hospital, not general hospital.
Pediatric hospitals have more suitable equipment and training for the specific needs of children.
Apply pressure to a bleeding wound. Support injured limbs with board or splinter, pillow or other soft object. You may lose your child's trust. Acknowledge what will probably hurt in a comforting, understanding way. Allow your child to express fears without judgment or ridicule, and let your child ask questions.
