Query: My 17-month son loves it!

I have Vol 1 to 3, my 17-month son loves them all. We started Vol 1 when he was 8 month-old. So glad that we let him learn sign language, he can't really talk yet. Therefore, he communicates with us by sign language. And he loves the "boy and girl" on this vol. Only thing I don't like this volume is the words they teach, I don't want my son to learn "Candy", "Ice Cream", "Cookies" etc all kind of "Junk Food". I tried to avoid him to eat junk food, but this vol exposes him to it.
