Merit School of Music in the west loop has a baby sign class. www.meritmusic.org
not all baby sign classes teach "fake signs," and if they do, so what? you're more likely than not doing this to help your child communicate with YOU as early as possible. chances are they won't remember many signs as their spoken vocabulary expands anyhow.
if you have limited spacial perception ability (like me) take a class. i can't figure out anything like knitting, signs, etc from looking at 2-D pictures. i have to see someone do it.
