This missive primarily spoke of the language aquisition stages of children. There are phases or milestones which a child reaches in languge development. According to the child, his upbringing and/or enviourment this development of course varies.
Watching my own child grow up I saw her language and speech abilities grow at a rapid pace. I used to speak to her from in the womb; my pediatrician says this helps very much in speech development. At the age of three she speaks mostly English but also words of Spanish & Taino. Her vocabulary really took off once she got to daycare and interreacted with other kids. She definatley has reached many milestones in her speech development and is continuing to grow day by day.
