This show, if anything, will slow down the development of a child. When the Teletubbies watch a little film clip in their stomach, thats fine... but then they do it "again!" Ask just about any child psychologist... repetition does nothing for a child except bore it. Children learn many times faster than adults, and they take in all that they are going to on one viewing, during the second one, they are just waiting for the show to get on with it. Maybe if you show it to them another day it might do some good, but not 5 seconds later. Also, this show is aimed at children that are still learning to talk, and the Teletubbies speak in a gibberish. Children are listening for words, trying to figure out what they mean and sound like so they can talk as well. Teletubbies will simply confuse them and slow down that learning process. The scenes are all dragged out too long and make the same point too many times. If you want your child to actually learn from what he sees, show him Sesame Street or something. Even letting the child sit in a room while you watch a soap opera is going to give them a better idea of the English language than this show.
