The Four-Month Sleep Regression

Parenthood is a journey filled with precious moments and milestones, but it also comes with its fair share of challenges. A common challenge that new parents face is the four-month sleep regression. In this blog post, we’ll explore the four-month sleep regression, why it happens, and, most importantly, how you can navigate it. We’ll also touch on the developmental changes that coincide with this sleep hiccup and what you can expect afterward.
What is the Four-Month Sleep Regression?
The term ‘sleep regression’ might sound alarming, but it’s a normal phase of infant development. At around four months of age, many babies experience a sudden disruption in their sleep patterns. Your little one, who may have previously been sleeping for longer stretches, might now wake up more frequently during the night.
Developmental Changes
Understanding why the four-month sleep regression occurs is essential. Around this time, your baby is going through significant developmental changes. They are becoming more aware of their surroundings and developing new skills. These changes can affect their sleep in several ways:
- Increased Awareness: Babies become more aware of their environment, which means they might become more easily startled or distracted during sleep.
- Rolling Over: Many babies start to roll over at this age. While this is an exciting milestone, it can disrupt their sleep as they may roll onto their tummy and find it uncomfortable.
- Changing Sleep Cycles: Your baby’s sleep cycles are maturing, and they may have difficulty transitioning between sleep cycles, leading to more frequent awakenings.
What to Expect Next
The good news is that the four-month sleep regression is temporary. As your baby continues to grow and adapt to these changes, their sleep patterns should stabilize. However, it’s important to note that every baby is unique, and the duration and intensity of the regression can vary.
How to Help Your Baby Through the Regression
Now, let’s dive into the most crucial part—how to help your baby navigate through the four-month sleep regression. Here are some evidence-based strategies:
- Establish a Consistent Routine: Babies thrive on routine. Try to establish a consistent bedtime routine that signals to your baby that it’s time to sleep.
- Create a Comfortable Sleep Environment: Ensure your baby’s sleep space is safe and comfortable. A firm mattress, a sleep sack, and a comfortable room temperature can make a big difference.
- Daytime Naps: Make sure your baby is getting enough daytime naps. Overtired babies often have more trouble sleeping at night.
- Respond to Your Baby: During the regression, your baby may need more reassurance. Respond promptly to their needs, but try to keep interactions calm and soothing to avoid stimulating them too much.
- Offer Comfort: Gentle rocking or soothing techniques can help your baby settle back to sleep during nighttime awakenings.
- Consider White Noise: Some babies find white noise soothing. A gentle white noise machine in the nursery can create a consistent background sound that may help your baby sleep more soundly.
- Consult a Postpartum Doula: If you’re feeling overwhelmed or exhausted, don’t hesitate to seek support from a postpartum doula. Bay City Doulas offers overnight support to assist you during this challenging time.
