Go to the library and find a book about firemen and firefighting. Read the book to your child a few times and write down the list of questions your child asks about how houses start on fire, who gets to be a fireman, and how they get to the fire so fast. Explain the responsibilities of the local firefighters and how to call them in an emergency. Call the firestation first to make arrangements and then take your child to visit. A firefighter will gladly show your child around and answer any questions. Make sure you ask to see the heavy jackets firemen wear and how they store their boots and pants all ready to jump into when the siren rings.
