As a counselor for families with young babies, I have had the opportunity to review a number of language programs (both sign and verbal) for preverbal babies and babies who are just beginning to verbalize.
As with Baby Wordsworth the production quality of this DVD is excellent, however the words and signs presented are not appropriate for either preverbal babies who are trying to communicate basic wants and needs or toddlers who are beginning to speak. Instead of offering words and signs such as eat, drink, milk, more, mommy, daddy, baby etc. - this program presents bank, florist, bakery, etc. Not only is the choice of words and signs questionable but the visual distinctions between scenes such as cafe, restaurant, and market is difficult for a baby to understand.
The format is also geared towards older children. Five words and signs are presented in rapid succession and then extended scenes for each word are shown. Then the same five words and signs are offered again by a child of four years or older. In addition, the signs themselves are difficult for young babies as most of the signs are combinations of more than one sign such as "ice cream" plus "store."
There are no babies signing or speaking in this production and no tutorial for parents of hearing babies who are teaching their babies to use sign language. I recommend the "My Baby Can Talk" series to teach either sign language or first spoken words to babies.
