See How We Can Help ↓What is the 4-Month Sleep Regression?
The 4-month sleep regression is a permanent change in your baby's sleep patterns that occurs around 3-5 months. Unlike other regressions, this one represents your baby's sleep cycles maturing to become more like an adult's. This means more frequent wake-ups and lighter sleep periods.
Common Signs:
- Frequent night wakings (every 2-3 hours)
- Short naps (30-45 minutes)
- Difficulty falling asleep
- More fussiness and crying
Why It's Different:
- Permanent sleep cycle changes
- Brain development milestone
- Increased environmental awareness
- Perfect time to start sleep training
Why 4 Months is the Perfect Time for Sleep Training
While the 4-month regression can be challenging, it's actually the ideal time to establish healthy sleep habits. Your baby's sleep cycles have matured enough to learn independent sleep skills.
