Anything can be "bad" or "detrimental" in large doses and I think the problem with walkers is that, well, there are no shortage of "stupid parents" out there who might just find it convenient to stick their kid in a walker all day long and just forget about them. But you get that with a lot of things, whether it's TV, or sugary snacks, or whatever, too much, too often is never a good idea. It *IS* important though to make articles like this and sometimes it's equally as important to over exaggerate a bit on the real "dangers" of it, the point being that "stupid parents" are more perceptive to the "shock and awe" approach. Those of you screaming that it's "garbage"...you really missed the point...and you're not helping anyone.
