Let your children know they can come to you with questions. Some guidelines to help you become an "askable" parent are:

Let your child know he or she can come to you for information.
Be willing to repeat information until your child understands.
Check out what your child already knows by asking what he or she thinks.
Keep your answers simple. Think about what your child can and can't understand.
Realize it's OK to say, "I don't know." There are many good books for you and your child to read together.
Relax.
Have a sense of humor

You want your child to come to you with questions rather than seeking answers from friends or television.
