The Truth About the 4-Month Sleep Regression

baby sleep regression

If you’re a parent of a baby around four months old, you’ve likely heard about the infamous 4-month sleep regression. But is it real, or just another parenting myth? Rest assured, it’s very real, and understanding what’s happening can help you navigate this challenging but temporary phase.


What is the 4-Month Sleep Regression?

Yes, the 4-month sleep regression is a real developmental milestone. Around this age, your baby’s sleep patterns begin to mature. They transition from the newborn stage of deep, almost constant sleep into more adult-like sleep cycles with lighter stages of sleep.

Common signs of the 4-month sleep regression include:

  • Frequent night waking.
  • Shorter naps or trouble falling asleep during the day.
  • Increased fussiness, especially during the evening.

This regression is a sign of progress, showing that your baby’s brain and sleep habits are evolving. For additional guidance on baby sleep stages, visit Raising Children Network.


Why Does the 4-Month Sleep Regression Happen?

The 4-month sleep regression is caused by significant neurological and developmental changes, such as:

  1. Evolving Sleep Cycles: Babies develop distinct light and deep sleep phases, which makes them more likely to wake during the night.
  2. Physical Growth Spurts: Increased hunger and the need for more energy can disrupt sleep.
  3. Heightened Awareness: Babies become more curious about their surroundings, making it harder for them to settle.

These changes, though frustrating, are essential for your baby’s growth and development. Learn more about baby sleep positioning here.


How to Navigate the 4-Month Sleep Regression

1. Establish a Calming Bedtime Routine

Consistency is key. A predictable, soothing bedtime routine helps your baby associate these steps with sleep. Include:

  • A warm bath.
  • A calming book or lullaby.
  • Swaddling with the Calm Babies Sleep Swaddle, designed to promote a secure and restful sleep.

2. Adjust Your Baby’s Sleep Environment

A comfortable sleep space can help minimize disruptions:

  • Use blackout curtains to block light.
  • Add a white noise machine to mask household sounds.
  • Ensure the room is cool and comfortable.

3. Follow Your Baby’s Lead

Pay attention to tired cues like eye-rubbing, yawning, or fussiness. Adjust nap times as needed during this period of transition. Follow Calm Babies for advice on managing daytime sleep.

4. Provide Comfort and Support

Your baby might need extra cuddles or more frequent feeds during this regression. Meeting their needs can help them feel secure and reduce night waking. Visit the Australian Breastfeeding Association for guidance on feeding during growth spurts.
