How can i teach my child the ABC's?

most children learn fast but some take slower because they are new to things. So you need to award them for completing something or if they are improving. Use a method in a way to make them want to work harder. Learning A B C's is like learning a new language for them because they have never heard of it. Try talking to them more and change the Words into an easier Word but same meaning. Also practice with them everyday because they have little thought and smarts so if you practice once in a while they will forget and not remember.

Try some ABCs Games such as memory and match game.
