Though development may differ from child to child, here are the stages that children generally go through when they become aware of sexuality. At age 3 to 4, children begin to ask where babies come from. They explore other children's and adults' bodies because of their curiosity. Children begin to have a sense of modesty and can begin to understand the difference between private and public behavior. By ages 5 to 7, children have increased need for privacy while bathing and dressing.
Girls become closer to their mothers and boys to their fathers.
When a three-year old asks where babies come from, you can say, 'They grow in a special place in the mother's body called a uterus. It will not be until later years when the child will ask what caused the baby to grow there in the first place. At that time, you can them explain the father's role in this process. Monitor the kinds of television programs your child watches and limit exposure. Be on hand to answer questions your child may ask about any programs he or she sees.
