Signing Time DVD's are the best products out there. I have rented many different signing and/or language DVD's from our local library before deciding to invest in this product. These are the only ones that my daughter will watch from start to finish & actively participates in. She is 1 yr old and already signs and recognizes many of the words. I think they are for children ages 3 mo - 5 yrs for those of you looking for a great and enjoyable teaching tool.
They keep the child entertained while still being educational.
