Many parents notice sudden sleep disruptions around the seventh month, even if their baby slept well before.
This temporary phase is known as the 7-month sleep regression.
It is a normal and temporary part of infant development.
Understanding the 7-Month Sleep Regression
The 7-month sleep regression describes a temporary disruption in a baby’s sleep patterns that usually occurs between six and eight months of age.
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
- Fighting daytime naps
- Difficulty falling asleep
- Shortened morning sleep
- Increased fussiness or clinginess
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.
These skills may include sitting independently, crawling, rocking on hands and knees, or pulling to stand.
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.
Duration of the 7-Month Sleep Regression
This regression will pass with time.
For most babies, it lasts between two and four weeks.
Consistency often speeds up recovery.
7-Month-Old Sleep Requirements
On average, a seven-month-old baby needs between 12 and 15 hours of total sleep per day.
- Night sleep: 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
A calming bedtime routine signals sleep time.
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
Daytime practice reduces nighttime activity.
Respond Consistently at Night
Gentle reassurance often works best.
Conclusion
This phase can feel challenging, Look At This but it will pass.
Your baby is developing exactly as expected.
Better sleep is ahead for both you and your baby.
