Even when you’re not saying anything you pass the information about these things to your kid.
Your behaviour affects your child in many ways – starting from your attitude about being naked in the house till our experiences in marriage and relationships. It means that the kid will see the difference between what you say and what you do (if it exists), more and more with years passing.
Sometimes it is difficult to find the right words. In some families fake names (their own names) are made up for intimate parts of body. Still, as the child becomes older, you’ll have to teach him the real names as well – for the child to cope with the real world.
