These programs are amazing in their simplicity, monotony, annoying high pitch xylophone playing, hypnotizing, mind numbing way. But apparently, that is exactly what the little developing mind needs. All three of my children have watched and loved these programs in their infancy and just tonight The Snake requested that we watch one. He is a toddler now but, the DVD had the same effect on him that it did when he was a baby. No sooner had I clicked play, did he drop into a zone like trance and didn't move a muscle until the show was over. And this it what it looked like, for 30 min. strait, he didn't move.
and that is why the creators of these programs are the wealthiest people on the planet.
