Children absolutely love these. This software is both far better and far worse than television. Use them as an enrichment, but don't let them substitute for your praise, your attention, your involvement. Don't let them supplant the wonder of the real world all around us. Play is your daughter's job.
Toys are powerful tools.
Nevertheless, don't be lulled into the misconception that more is better. More toys, more lights, more sounds, and more money do not make for a happier or healthier child. Many studies have shown that even the most deprived environments are full of opportunities for play. If the toys are versatile, and someone is willing to play along, children with fewer toys will often experience even more delight and creativity. Children need safety, freedom, loving attention, and praise.
