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
- Sudden nap resistance
- Difficulty falling asleep
- 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
Rapid Development
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
Many babies develop separation awareness at seven months.
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.
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
Longer wake periods are common official source at this age.
Encourage Daytime Practice
Daytime practice reduces nighttime activity.
Be Consistent With Night Wakings
Gentle reassurance often works best.
Conclusion
Sleep disruptions at seven months are normal.
Your baby is developing exactly as expected.
Better sleep is ahead for both you and your baby.
