Understanding the 4-Month Sleep Regression
The 4-month sleep regression is a normal developmental phase where babies experience disrupted sleep patterns. It typically lasts 2-4 weeks and signals brain maturation.
What is the 4-Month Sleep Regression?
Around 4 months of age, many parents notice their previously good sleeper suddenly waking frequently at night and fighting naps. This is commonly called the 4-month sleep regression, though it's actually a progression in brain development.
Why Does It Happen?
Your baby's sleep cycles are maturing to become more adult-like. Instead of two sleep stages, they now cycle through four distinct stages. These transitions between stages can cause brief awakenings.
Signs of the 4-Month Sleep Regression
- Increased night wakings - Shorter naps - Fussiness around sleep times - Changes in feeding patterns - Increased clinginess
