Actually you could throw in more languages for the child to learn. In studies it was shown that babies or young children can pick up languages better. You can teach them both that would be the safest so they would know more than one language. A young kid can learn up to a certain amount of languages. I forget what the number was but it's definitely more than two.

Any local will tell you the safest baby formula is from outside the country. They pay more money to import it. As for language, you can teach the baby both languages at the same time, it shouldn't be a problem. Teaching both from birth means the baby will be truly bilingual.
