What Is the 5-Month Sleep Regression?

 

The 5-month sleep regression is a period of increased night wakings, short naps, and difficulty falling asleep. It’s caused by:

• Developmental leaps – Your baby is learning new skills like rolling, reaching, and babbling, which can disrupt sleep.
• Changes in sleep cycles – Their sleep is becoming more structured, leading to lighter sleep and more wakings.
• Increased awareness – Babies at this age are more distracted, making it harder to settle at bedtime and naptime.
• Not every baby experiences a full regression, but if sleep suddenly changes around this time, this could be why.

 

 

 

Signs & Symptoms of the 5-Month Sleep Regression

If your baby’s sleep has suddenly changed, here are the most common signs:

 

Nighttime Sleep Struggles

• 5-month-old suddenly not sleeping – More frequent night wakings.
• Falling asleep takes longer – Your baby may need more help settling.
• Restless sleep – Tossing, turning, and waking between cycles.

Napping Issues

• Shorter naps – Your baby may take 20-30 minute naps instead of 1-2 hours.
• Fighting naps – Increased nap resistance (even when overtired).
• Inconsistent nap times – One day they nap well, the next day they refuse.

Tip: At this age, wake windows should be 2-2.5 hours before naps.

 

 

Common Sleep Issues at 5 Months

 

 

Not Sleeping Through the Night

 

It’s normal for babies to still wake at night, but if your 5-month-old was sleeping longer stretches and suddenly isn’t, it could be due to:

• Developmental changes – They are learning new skills and waking more.
• Increased hunger – A growth spurt may cause more night feedings.
• Sleep associations – If they need rocking, nursing, or holding to sleep, they may struggle to settle without it.

 

💡 Tip: If your baby is waking every 2 hours, check if they are relying on sleep props (rocking, feeding) to fall back asleep.

 

 

Frequent Night Wakings & Restless Sleep

• If your baby is restless at night, it may be due to: ✔ Practicing new skills (rolling, kicking, babbling). ✔ Discomfort from teething or digestion issues. ✔ Overtiredness from missed naps.

Tip: Give your baby plenty of floor time during the day to practice rolling and movement, so they don’t feel the need to do it at night.

 

 

How Long Does the 5-Month Sleep Regression Last?

 

Most sleep regressions last 2-6 weeks, depending on how quickly your baby adapts. If sleep struggles last longer, check for:

• Overtiredness – If naps are too short, night sleep will be affected.
• Sleep habits – If your baby is rocked or fed to sleep, they may struggle to link sleep cycles.
• External disruptions – Travel, illness, teething, or growth spurts can extend the regression.

 

 

How to Help Your Baby Through the 5-Month Sleep Regression

 

1. Follow Wake Windows & Sleep Cues

• Keep wake windows 2-2.5 hours before naps.
• Watch for yawning, rubbing eyes, and fussiness as sleep cues.

 

 

2. Create a Consistent Bedtime Routine

• • A calm, predictable routine signals that it’s time for sleep.
  • Keep bedtime between 7:00 – 8:00 PM.
  • Use dim lights, white noise, and a soothing activity (book, cuddle, lullaby).
  • Make a 5 month sleep schedule.

 

 

 

3. Encourage Self-Soothing (When Ready)

 

•  At 5 months, babies can start learning to fall asleep independently.
• If they rely on rocking or feeding to sleep, try reducing help gradually.

 

 

Tip: Try the Sleep Lady Shuffle—stay near your baby while they fall asleep, offering gentle reassurance without creating new sleep habits.

 

 

4. Keep Night Wakings Low-Stimulation

• Avoid bright lights and active play.
• Keep interactions calm and brief.
• If feeding, make sure baby is actually hungry, not just waking out of habit.

 

 

5. Be Patient & Stay Consistent

• Sleep regressions pass, but consistency helps shorten them.
• If sleep training, stick with a method for at least a week before making changes.

Yes! While not as well-known as the 4-month regression, many babies experience a sleep disruption at this age due to developmental changes and shifting sleep patterns.

How Long Does the 5-Month Sleep Regression Last?

Typically 2-6 weeks, but consistency is key to helping your baby through it.

How Can I Get My Baby to Sleep During a Regression?

• Keep wake windows appropriate (2-2.5 hours).
• Offer extra daytime feeds if hunger is causing more wake-ups.

The 5-month sleep regression is a sign that your baby is growing and learning new skills! While sleep might feel unpredictable for a few weeks, staying consistent and using gentle sleep strategies will help your baby get back on track.
