The Today Show presented these myths about getting baby toys that is right on the money. I applaud them for doing their homework.
Out of all the myths, I think one of the most important ones is the myth of the ABC's. Baby's are in sensorimotor stages of development so they are not going to get much academic worth out of toys that emphasize that. They need sensory stuff: things they can touch, feel, smell, gum, and hear. Even more vital is having a toy that is an acessory to their "main toy"(the parent). No purchased toy is worth any money unless it requires an adult to interact. Baby's need to establish trust with interacting with positive nurturing adults. Toys that promote isolation and passivity(videos, for example) shortchange the child.
