You can start by letting the kid read about the bible and God's stories for kids. At a young age, the kid will know how everything about the creation of everything on earth and the teachings of God at his/her age. Books, videos, or stories on how to eat properly, washing of hands, brush of teeth, wear clothes, and what to do before sleeping. Stories about relationships to deal with elders, siblings, or friends. If you can find any interesting stories or videos that will make the kid learn these simple things. Kids can easily pick up these at a young age. It is better to teach the kid using different tools for him/her to learn the right basic teachings for growing up kids.
