Where do babies come from mom/dad? The question coming from your child’s mouth might be a difficult one to answer for you. The following is the best reply I’ve come across.
First, establish the basics: A woman has a vagina and a man has a penis. (Do this using your own approach)
Second, establish that the female has a special place in her: A woman has a holy space in her vagina where God is. This place has to be protected and kept clean. Only a woman’s husband may enter this space as he loves her and the bond between husband and wife is pure and sacred. No one else may enter this space as it would upset God.
Third, the act of conceiving: A husband’s penis will enter the female’s vagina and if God believes the time is right, He will send love and energy into the vagina’s special place so that a baby starts growing in this special place.
Forth, the warning: If anyone else were to try and enter this special place it would make God very angry. If this happens, the child should bite, scratch, hit or scream and get away very quickly to get help and contact her parents.
(The necessity to explain the 3rd section so explicitly is so that the child understands very well when the child is to be violated making the warning in the 4th section more relevant and leaves no space for misunderstanding)
Light, Life and Love of the God of my heart be with you all !
