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.
