K'sM, That sounds like a legit concern. In my son's case, the Tag hasn't detracted at all from his reading. I'd have to say it enhances it. He reads plenty of other books to himself. And when he reads to me, he'll point out what each character in the picture is saying (imitating the Tag, LOL) But once a week or so, he still enjoys using the Tag. (Often on Sunday morning -- I get to read the paper and he grabs Tag books. Hurrah!). Actually, at this point, he mostly uses the sounds and games. I think he'll naturally use it less as he moves into deeper reading.
