As a parent, you’ve likely enjoyed some longer stretches of sleep from your little one, perhaps even settling into a consistent nap routine. However, you might find yourself back in the sleepless nights zone, as your baby begins waking frequently and fussing like a newborn again. This sudden change could mean you’re facing the 4-month sleep regression—a common phase in your baby’s development that can leave you feeling utterly exhausted.
“This period can be particularly challenging for parents, especially if their child previously slept for five to six hours continuously and is now waking up several times a night,” explains Dr. Emma Hartley, a pediatrician based in San Francisco and a member of our expert review team.
What is the 4-Month Sleep Regression?
Around the age of four months, many infants experience significant changes in their sleep patterns, which can be attributed to their developing brain. During this time, babies shift from a newborn sleep cycle to a more adult-like sleep pattern, which includes lighter sleep and more frequent awakenings.
How Long Does It Last?
Typically, the 4-month sleep regression can last anywhere from a few days to several weeks. It’s important to remember that this phase is temporary, and your baby will eventually settle back into a more predictable sleep routine.
Causes of the 4-Month Sleep Regression
The primary reason behind this regression is the maturation of your baby’s sleep cycles. As they move into lighter sleep, they may wake more easily and need assistance to fall back asleep. Other factors, such as teething or developmental milestones, can also contribute to disrupted sleep.
Signs Your Baby is Experiencing Sleep Regression
Look for these signs that your baby might be going through the 4-month sleep regression:
- Increased wakefulness during the night.
- Shorter naps during the day.
- More frequent fussiness or crying.
- Difficulty falling back asleep without assistance.
Tips for Managing the 4-Month Sleep Regression
- Establish a Consistent Routine: Maintain a calming bedtime routine to signal to your baby that it’s time to sleep.
- Create a Comfortable Sleep Environment: Ensure your baby’s sleep area is conducive to rest, with a dark, quiet, and cool environment.
- Respond Calmly to Night Wakings: When your baby wakes, offer comfort but try to avoid picking them up immediately. This can help them learn to self-soothe.
- Consider Sleep Training: If you feel comfortable, you might explore gentle sleep training methods to help your baby learn to fall asleep independently.
