Preschool children are curious by nature. The world is a new place to them. They are excited to see and try new things. This includes talking to strangers, which can be an uncomfortable experience for parents because despite educating your preschooler, he or she may talk to strangers again.
One of the most important things to remember is that there are good strangers and bad strangers. Good strangers are what you can consider "community helpers," like police officers, firefighters, mail carriers, and even teachers. You can explain to your preschooler that those good strangers are available for help, if they ever need it. Bad strangers may be anyone you do not know or are not community helpers.
Explain to your preschooler that he or she must always ask you, dad, or caregiver if they can talk with a grownup they do not know.
Constantly remind your children about strangers to be sure it is enforced. Be creative when teaching them about stranger danger.
