Hi There, Thanks for asking. Childhood onset OCD
usually begins around the age 10 to 12 or sometimes in the years after. For many of them a family stress
exists which contributes to the maintenance of symptoms. On the other hand, many children have some behaviors to show their autonomy (sometime by such behaviors you described). These behaviors manifest around age 4 and then gradually subside. However, it could be a sign that the child has a transient anxiety
about a family or social stressor. I wish you a good health.
