Parents should be frank with the explanation and avoid using any type of false scenarios, such as that of a stork leaving a baby at its door. Parents should explain what sperm and ovaries are, and how a single sperm comes into contact with and fertilizes an ovary. Next, parents should explain how it takes about 9 months for the child to develop. If the child is a girl, it should be explained to her that all types of non-prescribed drugs and alcohol should be avoided in order to prevent birth defects during developmental stages. Then parents should mention how a woman goes into labor after about 9 months have passed. This should cover the majority of questions a child may have about where babies come from.
