Around seven months, it is common for babies to experience unexpected sleep difficulties.
This stage is commonly referred to as the 7-month sleep regression.
This regression is completely normal and developmentally appropriate.
What Is the 7-Month Sleep Regression?
The term 7-month sleep regression refers to short-term sleep disturbances that often appear around the seventh month.
During this time, babies may wake more frequently at night or struggle with naps.
This regression is closely linked to rapid physical, cognitive, and emotional development.
Signs Your Baby Is Experiencing 7-Month Sleep Regression
Although symptoms vary, certain patterns are very common.
- Frequent night wakings
- Sudden nap resistance
- Trouble settling at bedtime
- Shortened morning sleep
- More irritability during the day
If these changes appear suddenly and your baby is otherwise healthy, sleep regression is likely the cause.
Causes of the 7-Month Sleep Regression
Developmental Milestones
At this age, major developmental leaps occur.
New abilities often include crawling attempts, sitting up, and improved coordination.
Nighttime sleep can be disrupted by mental and physical practice.
Separation Anxiety
Emotional attachment becomes stronger during this phase.
Babies may wake at night to check if their caregiver is nearby.
Changing Sleep Needs
Older babies require different sleep timing.
Most babies transition to two or three naps per day with longer wake windows.
How Long Does the 7-Month Sleep Regression Last?
This regression will pass with time.
For most babies, it lasts between two and four weeks.
With consistent routines, improvement may happen sooner.
7-Month-Old Sleep Requirements
Total daily sleep needs useful content remain relatively consistent.
- Overnight sleep: about 10–12 hours
- Day sleep: 2–3 naps totaling 2–3 hours
Proper sleep balance supports healthy development.
How to Survive the 7-Month Sleep Regression
Stick to a Predictable Routine
Consistency is more important than complexity.
Simple steps like a bath, pajamas, feeding, and a book can help.
Adjust Wake Windows
Most babies do best with wake windows of 2.5 to 3 hours.
Encourage Daytime Practice
Allow your baby to practice new motor skills during the day.
Respond Consistently at Night
Gentle reassurance often works best.
