The book said the optimal time to begin is when the baby first has visual tracking, or the ability to follow moving objects with the eyes, so I plan to start using them now...~~
My friend bought me "your baby can read" dvd too, I tried to play the dvd to my bb while she was 3.5 mos old, but she just cannot concentrate on the tv, will keep moving here and there after few words....
But I tried to play the dvd again these days (she is 4.5 mos old), she can almost concentrate on the whole dvd (starter). So I think this is the good time to let her watch it. But I am afraid that it is not good for baby to see tv too much, so I only play the dvd to her 3 times a week and 15 mins each time at most.
