When must i get professional help for my child if he has stranger anxiety?

When it's a problem.: Some anxiety (shyness) with strangers is normal and good. You want your child to be cautious with strangers. Honor the child's discomfort with anyone being too intimate. But if the anxiety is causing problems or distress in the child's life, talk to a professional as soon as possible to help decide what needs to be done. The sooner the issue is addressed, the easier it is to resolve.

Stranger anxiety -: A term used mostly with infants and their fear of unknown people - nothing to do there but wait until the period ends on its own. In older children, professional help should be obtained only when school refusal, agoraphobia, or other avoidance-of-people situations occur on a regular basis.
