Check this out... apparently he is involved in the parenting video business as well, only under a different name, "Mac Strider". So he purports to be an experienced parrot trainer, dog trainer, and now, apparently, is an authority on child rearing. Only, he's doing that under a different name. This counts among "things that make you go hmm..."
Check out this video, he's wearing the same t-shirt, is behind the same table, and the camera is at the same angle as in a parrot-training video. This is disturbing to me. I've posted both videos here:

I'm willing to bet he made both videos on the same occasion. This guy gives me the creeps. I wouldn't buy anything from either "Chet Womach" or "Mac Strider".
