Your child's cortisol is not a problem you need to manage — and most of the scary sleep advice that says otherwise is built on a misreading of the science. Craig and Arielle take on the claims that spread fastest online and hold up worst: the "overtired baby floods with cortisol" story, rigid wake windows, the 3-6-9 rule and the Wonder Weeks, magnesium lotions, melatonin as a quick fix, and the "biologically correct" 7 p.m. bedtime. It's an episode about why simple, absolute rules go viral while real answers — nuanced, and dependent on your actual child — do not. They close on the hardest question a tired parent faces: in an unregulated field full of confident strangers, how do you tell a trustworthy sleep expert from a good marketer?
