This guidance is beyond suspect. It falls into the category of "drink 8 glasses of water a day." Doctors parrot it, but they have no foundation for saying this and no one knows when/why they started saying it. But they all say it.

Any serious medical professional worth a damn will immediately question the SIDS "guidance." If you don't know what causes something, you can't treat it. You don't blindly run around doing things and hope it helps. You have to find out the cause to find the cure.

This is exactly the kind of FUD that people are fighting when dealing with crazy CPS zealots.

Edit: If SIDS is suffocating from an obstruction, then call it suffocation by obstruction. But it's not suffocation by obsstruction. The current theory is that it's suffocation due to brain malfunction. Putting a toy in a crib isn't going to cause a brain malfunction.
