She picked up a few words through watching Dora the Explorer but hasn't watched it for months and we haven't bothered keeping up with the spanish words.
That said, we've just bought her the Dora scrabble which has english and spanish and she has just correctly told me the meaning of around 10 words that I've said to her in spanish
Is it that easy for them to pick up another language at that age? (just turned 4) Is it a good time to encourage it and broaden the amount she learns?
