Landon Johnson had been trying to breast-feed almost continuously since his birth days earlier — and screaming each time his mother pulled him from her chest. Just stick with it, the first-time parents were told; it will take some time to get the hang of breast-feeding.

But hours after the Johnsons took their son home from the hospital, Jillian found him unresponsive.
