My granddaughter is 19 months old and has been watching Signing Time since she was an infant. It is the only program she wants to watch, much to our happiness. When she was 9 months old she would let us know when she was hungry by signing "eat", "milk", "more". Something that recently happened: She had been signing cracker by hitting closed fists together (similar to shoe). We knew what she wanted and continued to reinforce the correct sign when she received the cracker. While watching Rachel sign cracker, it was like a light coming on. She would sign it her way, then Rachel's way and after several times of doing it both ways, she started to sign it correctly and has since. Signing Time has been a blessing in our family with the great quality of the DVDs and the fun way sign language is taught, and the way it has given our family a great tool to communicate with our little one. Thank you, Signing Time! Keep up the fantastic work with helping families and children.
