I am not a teacher, but am wanting answers from teachers. I am thinking about purchasing the Your Baby Can Read dvd set. I have read some great reviews on the product but have also read some poor ones. The poor ones state that it is more damaging than beneficial to use the program because it teaches children to read whole words rather than to read phonetically. My son is 3 years old. I would love for him to get a head start but not if it will put him at a disadvantage when he gets to school. Will teaching him to read whole word at this age cause him to have a hard time once he is in school?
