Has anyone heard of this woman, the "baby whisperer"? What's she like?

A non gentle parenting friend of mine told me i should read her stuff and I'm wondering why, LOL Is it because she'd suit my style as a parent or because she thinks I need to be "taught' something? I had a look on her webpage which said basically the hypervigilance of not letting your kids cry is stopping them sleep - so maybe my friend thinks I need a message.

ANyone know of her?
