DH and I have been discussing the idea of introducing a second language (German) to the baby when he gets here. I'm fluent in German although I don't have any parental/cultural background in it; I just spent time in the country and have studied and taught it for several years. Now, I know my German's good because native German speakers think that I am actually German when they meet me (always very flattering! ) but on the other hand, I'm aware of the fact that I do make mistakes and I'm worried that the child/ren will pick up on my bad habits. But I just feel that I'm so lucky to be able to have this extra skill, and I would love to pass it onto the baby and any other children we might have... on the other hand, it's a big commitment and I also worry about developmental delays in speech.

Do any of you raise your children bilingually? Pros, cons, advice would be most appreciated, thanks!
