What is a “potential OTD child”? You mean he (or she) is not really OTD but the parent is concerned that he or she might be in the future? Is this a case of counting chickens before they’re hatched?
Good communications between parent and child are just part of good parenting. You don’t have to wait until you think there’s a problem before you pay attention to your kids. Openness and communication are good parenting traits even if the bachurel is the local ilui, come to think of it, that’s when you need good parenting skills most.
As far as “potential OTD” goes, General Patton said it. “Do not take council of your fears.”
