Didn't mention, but start as early as possible. once kids are older, they will resist any sudden attempt at non-english. Also, don't worry about "speech development" (i.e late talking). Your kids may be slightly behind peers in speech, but they will catch up by age 2-3. Kids are like sponges, they learn everything quickly.
