This developmental DVD is the one that comes with a plush doll that interacts with the on-screen DVD presentation, encouraging babies to become more active participants instead of merely passive observers of television. Designed by noted behaviorist Dr. Osnat Emanuel, the DVD has a simple, harmless electronic signal that communicates wirelessly from your television to the cuddly doll. As the DVD plays, the plush doll reacts to the program, giggling, singing, and flashing its integral lights, which inspires the child to regard the doll and respond in kind. The doll, in turn, encourages the child's participation and provides positive reinforcement with age-appropriate vocabulary. Lamb (3 months to 12 months), Dog (3 months to 12 months), or Cow (12 months to 36 months). Runs on three AA batteries. Imported. Doll: 8" H. (1 lb.)
