See How We Can Help ↓What is the 3-Month Sleep Regression?
The 3-month sleep regression is a temporary period where your baby's sleep patterns suddenly change. This typically happens around 3-4 months and can last 2-6 weeks. Your previously good sleeper may suddenly start waking more frequently, fighting naps, or having difficulty settling.
Common Signs:
- More frequent night wakings
- Shorter naps (30-45 minutes)
- Difficulty settling to sleep
- Increased fussiness
Why It Happens:
- Brain development changes
- Sleep cycle maturation
- Increased awareness
- Growth spurts
How to Survive the 3-Month Sleep Regression
1. Maintain Consistent Routines
Even when sleep is chaotic, keeping bedtime and nap routines consistent helps signal to your baby that it's time to sleep.
- Same bedtime routine every night
- Consistent nap environment
- Similar timing for sleep periods
2. Focus on Sleep Environment
A optimal sleep environment becomes even more important during regressions.
- Dark room (blackout curtains help)
- Cool temperature (68-70°F)
- White noise machine
- Safe sleep space
3. Be Patient & Flexible
Remember that this is temporary. Some days will be harder than others, and that's completely normal.
