I have "passable" Spanish and BSL but i wouldn't say i could speak them per say. I would however like my son to grow up to be fluent in all three languages if possible but i don't really know how to go about it. He knows the basics like Numbers, Colours, Letters, a few animals, a few greetings, Please and Thankyou. But now i don't know where to go from here? Or if its best to teach them simultaneously or a chunk of one, then a chunk of the other? Or if this end up being a fruitless endeavor?
