What Is Sleep Regression in Babies and How Long Does It Last?
What Is Sleep Regression?
Sleep regression is when a baby who was previously sleeping well begins to:
- Wake up more frequently at night
- Resist naps or shorten them
- Struggle to fall asleep
It is usually linked to:
- Brain development
- Motor skill milestones
- Increased sensory awareness
Sleep regressions are not setbacks—they are signs of developmental progress.
When Do Sleep Regressions Typically Happen?
While every baby is different, common periods include:
Age |
Typical Triggers |
4 months |
Changes in sleep cycles, increased REM sleep |
6 months |
Teething, starting solids, separation awareness |
8–10 months |
Learning to crawl, sit, or stand |
12 months |
First steps, language development |
18 months |
Independence, big emotions, speech burst |
24 months |
Night fears, dropping naps |
During regressions, babies may wake more often, resist naps, or become clingy at bedtime.
How Long Does Sleep Regression Last?
- Usually lasts 2 to 6 weeks
- Duration depends on the baby’s temperament, environment, and how it’s handled
- With consistency, babies often return to their normal routine
Key to success: Stay calm, stay consistent, and trust the process.
Signs of Sleep Regression
- Frequent night waking after previously sleeping longer stretches
- Shortened or skipped naps
- Difficulty falling asleep
- Increased fussiness or clinginess
- Only sleeping while nursing or being rocked
How to Support Your Baby During Sleep Regression
1. Stick to a Consistent Bedtime Routine
- Include calming activities like bath, book, lullaby
- Keep bedtime and nap times as regular as possible
2. Avoid Rushing In Immediately
- Give your baby a moment to self-soothe before responding
- Avoid forming new sleep associations like constant rocking or feeding
3. Consider Underlying Needs
- Check for teething, hunger, or discomfort
- Offer brief comfort and soothing if needed
4. Don’t Skip Daytime Naps
- Overtired babies sleep worse at night
- Follow appropriate wake windows for your baby’s age
When to Seek Professional Help
Talk to your pediatrician or a sleep consultant if:
- Sleep issues persist beyond 6 weeks
- Your baby shows signs of fatigue, weight loss, or developmental concerns
- You feel emotionally overwhelmed or exhausted
In some cases, structured sleep coaching or a health check may be helpful.
