If a child does not understand what gay is but shows signs of being gay at first, does that make the child gay even if he or she doesn't know it?

Labels are no good: Parents often know before their children that something may be different with them. That difference may not be so black and white or what they assume. It is best to watch and wonder and wait. A child needs to know that no matter what they are loved, accepted and that their parents support them no matter what. Time will tell.
