Exposing your child to a new language is one of the best things you can do for them as a parent. Early foreign language learning helps with brain development and has proven to have positive long term affects. Children that were exposed to other languages as babies excelled in primary school subjects like English and math. Orgeonlive.com published an article entitled 'Helping Children Learn Second Languages' which offered great advice to parents who wanted to expose their children to foreign languages. A concerned father who uses a bilingual caretaker took notice of his 20 month old daughters progress. He says, "About a third of her 50 or so words are foreign, but sometimes says things in the foreign language we don't understand.I figure it's good for her brain to learn a second language even if it is one she'll never use as she gets older, or probably even remember. Or am I just confusing her?"  Portland Principal Maria Abad of the Internationale School which teaches language immersion courses in French, Spanish, and Mandarin Chinese to children as young as three reassures the parent.  "Exposing your children to more than one language is never confusing."  Simply put your child does not have to understand that they are learning more than one language especially at such a young age. The simple fact that they are getting the exposure is beneficial anyway you look at it. 

The outcome of early exposure to language education paves the way for success in the future. For example children will learn to become more accepting  of different cultures and customs,  they're more willing to try new things  and overall are more adjusted globally. Principal Maria Abad cautions against children being exposed to too many languages at once. Children wont be able to associate the many sounds that come with learning multiple languages. Choose one language and stick with it! 

This article is loaded with helping hints and useful material for parents that are teaching their children a second language. Perhaps the best and most rewarding experience I've had in the course of teaching my daughter Spanish is seeing her use it in natural conversation. At bed time now she alway says "Buenos noches te quiero  mama" for "Good night I love you mommy" which is always the perfect way to end a day no matter what language she says it in.
