Wind-Down Period Before Sleep

The Wind-Down Is Not the Routine

The wind-down period is what happens before the bedtime routine begins. Think of it as the transition between the active evening and the structured routine. It typically covers the 30-60 minutes before you start bath or pajamas, and its goal is to gradually lower your child's arousal level.

Why It Matters

Melatonin, the hormone that promotes sleep, is triggered by dim light and suppressed by bright light — especially blue light from screens. A proper wind-down period allows melatonin to rise naturally, making it physically easier for your child to fall asleep. Skipping it and going straight from rough play or screen time to bed is like asking someone to fall asleep right after a workout.

What to Do

• Dim the lights in your home 30-60 minutes before bedtime. Switch to warm, low lamps instead of overhead lights.
• Turn off all screens. The AAP recommends no screen time for at least 1 hour before bed for children of all ages.
• Switch to calm activities: coloring, puzzles, blocks, reading, gentle play, or talking about the day.
• Lower the volume — speak more quietly, turn off music or switch to soft, calm music.
• Offer the last snack or milk during this period (for toddlers), so hunger does not disrupt sleep later.
• Avoid roughhousing, tickling, chasing games, or anything that gets your child wound up and laughing hard.

Screen Time and Sleep

Research consistently shows that screen time before bed delays sleep onset, reduces sleep quality, and shortens total sleep. The blue light emitted by screens suppresses melatonin production. But beyond the light, the content itself is stimulating — even "calm" shows activate the brain in ways that oppose sleep readiness.

For Babies vs Toddlers

Babies under 12 months need less structured wind-down — dimming lights and moving to quieter activity is usually sufficient. Toddlers and preschoolers benefit from a more intentional transition, especially if they tend to get hyper in the evening. A timer or visual cue ("when the lamp turns yellow, it is wind-down time") can help toddlers understand the shift.
