The Dora effect

My son who is now four is getting Spanish lessons in the nursery once a week and his father is trying to speak Spanish with him on a regular basis but my son has shown no interest whatsoever in learning the language. He only wants to speak Swedish and has even become angry when I or anyone else have asked him what certain words are in Spanish or in English. Until now I should say as now he has discovered Dora the Explorer, which are computer games and films where a little dark-haired girl speaks both Spanish and English and asks the player/viewer to repeat her words and expressions. To my great joy this Dora character has made my son really interested in languages all of a sudden and yesterday he asked me what different words in Swedish were called in Spanish and English! I am so glad that he can take this with him, that is learning languages at such an early age - he will have so much for free later on. Talk about Dora effect!
