1. When your kid is overtired, her body releases a stress hormone called cortisol, which can make it harder for her to settle down. Move up bedtime 30 minutes to avoid that inevitable trip into overdrive.
2. Little kids experience FOMO too. So don't start Dance Charades minutes before lights out or talk about what older siblings will do once the young ones are in bed. Create a consistent (even slightly boring) routine to lull them into a relaxed state.
3. While watching a show may seem like a good way to unwind, too much screen-time can backfire. Studies show the blue light from screens delays the release of sleep-inducing hormone melatonin, and can affect the quality of sleep.
