Some people may think it is odd I would benefit from this program being that I am already fluent in American Sign Language. With my first child I did not utilize any resources while teaching her to sign and while she picked up a large vocabulary we had some pitfalls along the way. Plus I did not even realize all the different scenarios in which to provide new signs for my daughter. This time around with my son I've seen a difference in teaching him useful signs earlier than I would have thought he could understand their meaning, such as "help" and "hot". The years of research and knowledge provided in this complete kit definately benefits parents just starting out with signing to their baby/toddler. Parents in my workshops and classes using this kit have also stated it has made a great impact on their lives. Sign4Baby .... everyone should do it!
