I live in Medellin, Colombia and for a few weeks I was teaching an ESL kids class once per week to a couple of 3 year old kids. You might be thinking, wow! That’s a really young age to teach someone a new language! But is it really? People are exposed to language from the moment they are born, usually the language they will grow up speaking natively. The parents spend their day speaking to their child and eventually the child picks up on the language and learn grammar while in school.
