Super Start should be only a small part of the process. It's only intended as a tool to help kids obtain rote-memory information. The idea is to produce an almost constant but gentle input of sound and visual stimulation with a great deal of variety, but not to over-stimulate. There are clues to over-stimulation. Watch for signs of habituation.
Variety helps here.
Also look for overexcitment and crankiness. Lay off a while if either happens, and re-check to make sure Super Start is in the background where it belongs. And don't forget playing and loving. Experts suggest that in your child's first year of life, you introduce her to objects of different weights, textures, and materials, for example, and show her colors both indoors and outdoors. Because babies tune in quickly to sounds and rhythms, read poetry to your baby and have her listen to all kinds of music.
