We used Baby Bumble Bee videos. My mother in law bought the whole set for us when my daughter was probably only about 1. My daughter loved it and is 6 now and still watches it. I don't know if it was the only thing that influenced her but she is only at the beginnning of 1st grade now but reads at a high 2nd grade level and knows more words than any other kid in her class. I believe it can be ordered online.
