7-Month Sleep Regression Explained: How Long It Lasts and How to Survive It
If your baby was sleeping well and suddenly starts waking more often, fighting naps, or resisting bedtime around seven months, you are not alone.
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
- 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
Seven-month-old babies experience rapid growth and learning.
New abilities often include crawling attempts, sitting up, and improved coordination.
Nighttime sleep can be disrupted by mental and physical practice.
Separation Anxiety

Babies may wake at night to check if their caregiver is nearby.
Schedule Adjustments
Older babies require different sleep timing.
Wake windows typically extend to 2.5–3 hours.
Duration of the 7-Month Sleep Regression
The good news is that this phase is temporary.
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 look these up of total sleep per day.
- Night sleep: 10–12 hours
- Daytime naps: roughly 2–3 hours
Adequate sleep reduces nighttime disruptions.
