How do you take a temperature on a child age 7?

Kiss or touch your child's forehead. If you think he feels hotter than normal, you're probably right.

A fever is usually a sign that the body is waging a war against infection. Taking your child's temperature can confirm your suspicions and help you and your child's doctor figure out the best way to get your child back on the road to health.

Most doctors – and the American Academy of Pediatrics – agree that a normal body temperature for a healthy child is between 97 and 100.4 degrees Fahrenheit (36 to 38 degrees Celsius). If your child's temperature is above this range, he has a fever.

hope this helps :D
