PLAY METHOD OF LEARNING
The best way to teach early years or little children is using the play method.

You playfully introduce what you want them to learn without them knowing something serious is going on. That way they are more relaxed and learn easily without stress unlike you getting all serious and they find it boring and lose interest totally.
This is the method I use to teach my baby colours and part of the body. I make use of few minutes during weekends to tutor her as I am always busy during the weekdays. She's 1year and 5months but she's learning at a fast pace. She can now identify most of the body parts such as head,nose , eyes,ears, toes, chest,neck, fingers and shoulders.

By the time she is 2years, I will resign from work and Start homeschooling her probably in order to work on her reading skills. I believe I am going to achieve more with her with home schooling.
