Acquiring language and reading

After reading the wikipedia article i have to agree with James and Richard that the environment plays a role in aquiring language. The Mama teached me Talk article also states the same with better examples as to why the environment plays a role. In this article they speak of how the parents are the role models of language and they might not even realize it. Think about a child and how all they do is imitate language in their first couple of years of language. They say just about everything they hear. After years of this imitating they aquire this language to be theirs. This imitating now becomes their language. It may be proper, it may not be. But at three and four do these young children really know what is the proper language and what is not?

This then becomes a problem later on when it is time to read. The words that they hear might not look the same on paper. For example: a child calls the bathroom a bafroom for five years but when he/she sees the word bathroom written down on paper, it might confuse them. Here is this word that they have been using since they were probably two years old and it doesn't look anything like it sounds. As if the english language is not confusing enough, now they have to learn to read and correct their grammer (their language) at the same time.
