Children only go missing when parents are careless.

In my opinion, children never go missing if they are in under their parents' care. With parents' care, they can realize what is the right way to to go. In addition, when parents see any evident of going missing, they can hinder this action. Therefore it's so difficult to going missing when the children receive a lot of care from their parents.

Parents really cannot be in control 100% of the time. It only takes a couple of seconds for a child to be lost in a crowd, or worse to be abducted. Does this call for more use of reins, harnesses, or the child being strapped in a pushchair, depending on age and to what age?

The first school and learning place for a baby is the mother's hug and the family environment. If you give them good upbringing and teach them better ways how to live, definitely they can easily handle the remaining life by themselves.
