I have to admit I haven't read this book. Reading the available excerpt I found much common-sense advice, until the part about putting your infant to sleep on his stomach. This is dangerously outdated advice - used to be the accepted practice until about 15 years ago (the copyright is 1985!) when research showed much higher rates of SIDS (crib death) in babies sleeping on their stomachs. This makes me concerned about whether the other info is similarly outdated - babies' sleep needs haven't changed much in 20 years, but safety recommendations have.
