Make sure your child knows that you would never give them up, and that if they are ever taken from you, you will always search for them. Many children feel betrayed, and when they return they may need you to prove that you did search for them. Therefore, newspaper articles or anything else which may help to convince your child that you did try to find them can be helpful. Because the spirit of the law is the protection of the child, a consideration must be what the effect of a parent being convicted, and possibly imprisoned, would be on the child. It can be a very complex issue.
Some countries recognize no law but their own.
For example, a few years ago a teenager travelled to Iran with her father only to discover that under Iranian law she was his property and therefore could not leave without his permission. The Canadian Embassy was unable to help. After a few years, she eventually returned to Canada and her mother but only with her father's permission. There are several places that a parent of an abducted child can turn to for assistance. The best and most obvious place is the local police in your area.
