What is the 5 3 3 rule?

The 5-3-3 rule is a popular, parent-created baby sleep training method for night weaning and establishing consistent sleep, involving a baby sleeping for 5 hours, then being awake or fed for 3 hours, and then sleeping for another 3 hours, helping them align with circadian rhythms and learn to self-soothe by extending night feeds gradually. It's a flexible guideline, often used around 4-6 months old, to create structure and reduce frequent night wakings by delaying the first feeding and creating regular intervals, though some parents use it for cry-it-out check-in intervals (5 mins fussing, 3 mins comfort, 3 mins fussing).

How do navy seals fall asleep so quickly?

These techniques, practiced over weeks, train the body and mind to switch off rapidly, even under stress.

This method helps transition away from constant night feeds by setting minimum wake-up intervals (5 hours, then 3, then 3) before offering another feed, but it's crucial to ensure they're physically ready for less frequent feeding, notes The Bump and BabyCenter.
