Always carry your child's photo
Always carrying a photo, be it a wallet or on a mobile, is very useful if one day the child disappears from your surveillance. Especially if you had time to take a picture of the child on that day as well so that the color of clothes and accessories used by children can be drawn clearly. Showing the photos to the officers and the people around you makes your search easier.
The first thing you have to master is self-control and stay calm. Go back to where you've been before and look for places that are likely to attract children's attention.
For example, a doll or toy store, a fountain, near a pond, or a place where children of his age gather. If within 1o minutes of search, you can not find it, immediately ask for help from the employee or security officer. Describe the situation, child characteristics, and likes that are likely to interest him.
