Navigating The 4- Month Sleep Regression

Just when you feel like you've found your rhythm, everything changes.

Your baby is suddenly waking more often at night, naps have become short and unpredictable, and you're wondering what happened. If this sounds familiar, you're not alone.

The 4-month sleep regression is one of the biggest developmental changes in your baby's first year—but it's also one of the most misunderstood.

In this guide, you'll learn:

• Why the 4-month sleep regression happens (and why it's actually a sign of healthy development)

• What's normal during this stage and what to expect

• How your baby's sleep cycles are changing

• The role sleep associations play in frequent night wakings

• Gentle, responsive strategies to help your baby build healthy sleep habits

• Common mistakes that can unintentionally make this phase more challenging

Created by a NICU nurse, newborn educator, and mom, this guide provides evidence-based information without unrealistic expectations or one-size-fits-all advice.

Whether you're in the middle of the regression or hoping to prepare before it begins, this resource will help you understand what's happening, respond with confidence, and support your baby's sleep through this important developmental milestone.
