Re: bi lingual babies?
As a pp said, the younger the better. My nephew has a half brother that is 10 and can speak french english and spanish fluently. My SIL's DH is french and they speak to dd mostly in french, she seems to think it is funny and laughs at them. Personally, I can understand a little spanish but cannot speak it at all. I had a spanish nanny for a long time and I guess some of it stuck.
