The 4-Month Sleep Regression: What to Expect and How to Handle It

If you’ve been enjoying your baby sleeping through the night and then suddenly find yourself back to sleepless nights, your little one might be going through the 4-month sleep regression. Here’s everything you need to know.

What is the 4-Month Sleep Regression?

The 4-month sleep regression refers to a period when babies, who were previously sleeping well, suddenly face sleep disturbances around 4 months of age. This can cause shorter naps, more frequent nighttime wake-ups, and extra fussiness, often leaving parents frustrated and confused.

What Causes It?

The main causes of this regression are:

• Developmental Changes: Around 4 months, babies develop their circadian rhythms and move to more complex sleep cycles, similar to adults, which disrupts their sleep.
• Growth Milestones: Cognitive and physical growth spurts contribute to sleep disturbances.
• Routine Changes: Any changes in baby’s routine or environment can also affect their sleep.

Signs of 4-Month Sleep Regression:

• Trouble falling asleep for naps or at night
• Shorter naps and less daytime sleep
• Frequent waking during the night
• Extra fussiness and restlessness at bedtime
• Increased crying and desire to be held while sleeping

How Long Does It Last?

This phase can last anywhere from a few days to a few weeks, but it’s important to stay consistent with your baby’s sleep routine. The regression is temporary, and babies will usually return to more predictable sleep patterns.

Tips for Coping:

1. Establish a Consistent Bedtime Routine: Babies thrive on routine, so try to keep a regular schedule for naps and bedtime, even if things feel disrupted.
2. Make Baby’s Room Dark: This helps babies associate darkness with sleep, signaling that it’s time to sleep.
3. Put Baby Down Sleepy but Awake: Letting baby practice self-soothing helps them learn how to fall asleep independently.
4. Be Patient and Offer Support: If baby wakes up in the middle of the night, give them a few minutes to self-soothe before intervening.

When to Consult a Pediatrician:

• If baby experiences discomfort, has a fever, or seems unwell.
• If you notice a change in feeding habits or growth patterns.
• If sleep disruptions persist beyond the typical regression timeframe.

Final Thoughts:

The 4-month sleep regression is tough, but it’s a sign of your baby’s healthy growth and development. Stick with your routines, practice self-care, and remember—it’s just a phase!
