Decoding Newborn Sleep: Cycles, Cues, and the 6-Week Crying Peak

Welcome to the Most Mysterious Phase of Baby Sleep

If your newborn sleeps like a dream for a few days—then suddenly cries every evening—you’ve likely entered the 6-week crying peak.

Let’s unpack what’s happening.

Newborn Sleep Cycles

• Last 30–50 minutes
• Lots of active sleep (wiggling, noises)
• Short naps are normal
• Night feedings every 2–4 hours

Crying Peaks Around 6–8 Weeks

This is a developmental milestone, not a failure.

Babies cry more during this period because:

• Their nervous systems are still maturing
• They’re adjusting to day/night patterns
• They may be overtired or overstimulated

Tips to Cope

• Use white noise
• Dim lights after sunset
• Practice “cuddle, nap, drowsy”
• Take turns as caregivers
• Ask for help—it’s okay

Final Thought

The 6-week peak passes. Stay close, stay calm, and know that you’re doing it right—even when it’s loud.
