Babies Learn From Translations

Babies cannot learn from translation because they don't know another language. So babies learn from actions and situations plus language. This takes time, and most importantly, it takes a large amount of repetition. As adults, you learn in a similar way. You actually have some advantages as an adult that help you learn much faster than the baby. And this they learn grammar in exactly the same way. It's just a huge amount of listening and repetition in understandable situations. Trying to remember a lot of complicated grammar rules is like trying to go up the river...you're never going to succeed.
