The safety of the entire family usually seems to fall on Mom, but it's important for even the smallest family members to know what to do if disaster strikes. Whether it's an injury, crime or natural disaster, you can teach your children how to take control and get help when you're unable to do so. Start by teaching children as young as three your home phone number and emergency numbers such as 911. A fun way to ensure that he remembers the digits is to invest in some number-shaped cookie cutters and bake and eat cookies in the order of your number. Remember to teach children your address as well. Posting stickers or signs throughout the home, especially near phones, help keep that information fresh in their minds. Disconnect the phone and allow them to practice.
