Hi lex,
Okay, I haven't really heard of the programs you mention so I went to take a look and clearly these are right up there with "My Baby Can Read" or whatever that one is called. I don't put much stock into systems that force feed the knowledge. These programs seem to be a part of the movement of trying to give your child the leg up in the competition.
As for is it bad for him? Really depends. If the focus is only these programs and not leaving room for his creativity then IMHO it could be a problem.
Bottom line, for me anyway, is these are not programs that I would be interested in for my DD.
