What to say
Tell a younger child, "A baby is growing in Mommy's belly" or "When a mommy and daddy love each other very much, sometimes a new baby grows in Mommy's belly." Older children may benefit from a brief lesson in reproduction. Explain the process of a sperm and egg uniting to make a baby through an age-appropriate discussion.
Prepare yourself for any and all questions. Your child may be indifferent or could have many questions. Some questions you may encounter are, "How will the baby come out?" or "Will it hurt?" Be honest yet age-appropriate in your answers to questions. Lying only will create confusion for your child.
Keep the discussion of labor and delivery on her developmental level. Explain the pain factor and assure her you will be fine. After all, you delivered her and lived to tell the tale.
