What Is the 4-Month Sleep Regression, and How Can I Help My Baby Through It?

Summary of the Question:
"My 4-month-old has suddenly started waking up every 45 minutes to 2 hours at night, and I'm completely exhausted. Could this be the 4-month sleep regression I've heard about? How long does it last, and what can I do to make things easier for my baby—and myself?"


What is the 4-Month Sleep Regression?

The 4-month sleep regression is a common developmental phase when a baby's sleep patterns shift, leading to more frequent nighttime awakenings and shorter naps. Unlike the newborn stage, where babies easily drift between light and deep sleep, this stage introduces more adult-like sleep cycles, causing disruptions.

Parents often notice:

  • Frequent waking during the night.
  • Difficulty resettling after waking.
  • Inconsistent naps during the day.

These changes are normal and a sign of cognitive growth, as babies become more aware of their surroundings and develop new skills.


How Long Does the Regression Last?

Typically, the 4-month sleep regression lasts between 2–6 weeks, though it can vary. Some babies adapt more quickly, while others need extra time to settle into their new sleep patterns.


How to Manage the 4-Month Sleep Regression

Here are actionable tips to ease this challenging phase:

1. Stick to a Consistent Routine

A predictable bedtime routine signals to your baby that it’s time to wind down. Your routine might include:

  • A warm bath.
  • Gentle massage or quiet play.
  • Feeding and a calming bedtime story or lullaby.

Adjust the bedtime slightly (e.g., 7:30 PM) if you notice it aligns better with your baby’s sleep cues.

2. Encourage Restful Daytime Naps

Daytime sleep plays a crucial role in nighttime sleep. While naps might feel erratic, you can:

  • Put your baby down for naps in a dark, quiet room.
  • Watch for early signs of tiredness, like rubbing eyes or fussiness.
  • Use a white noise machine to minimize distractions.

3. Optimize the Sleep Environment

A soothing sleep environment can reduce night wakings:

  • Use blackout curtains to block out light.
  • Maintain a cool, comfortable room temperature.
  • Ensure the crib is safe, firm, and free of loose bedding.

4. Handle Gas or Feeding Issues

If gas is contributing to discomfort, try:

  • Feeding smaller amounts more frequently (e.g., 4 oz every 2.5 hours).
  • Burping your baby thoroughly after every feeding.
  • Offering gentle tummy massages to release trapped gas.

5. Minimize Stimulation at Night

When your baby wakes at night, keep interactions calm:

  • Avoid turning on bright lights.
  • Speak in a soft, soothing voice.
  • Limit feeding or diaper changes unless absolutely necessary.

6. Be Patient and Flexible

While this phase is exhausting, it’s important to remember that it’s temporary. Providing comfort and consistency will help your baby adjust over time.
