When should sex education start?

It is important for sex education to begin at a young age and also that it is sustained. Giving young people basic information from an early age provides the foundation on which more complex knowledge is built up over time. For example, when they are very young, children can be informed about how people grow and change over time, and how babies become children and then adults, and this provides the basis on which they understand more detailed information about puberty provided in the pre-teenage years. They can also when they are young, be provided with information about viruses and germs that attack the body. This provides the basis for talking to them later about infections that can be caught through sexual contact.
