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 stage is commonly referred to as the 7-month sleep regression.
This regression is completely normal and developmentally appropriate.
Understanding the 7-Month Sleep Regression
Sleep regression at seven months is a phase where previously stable sleep suddenly becomes irregular.
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
While every baby is different, many parents notice similar signs.
- More disrupted nighttime sleep
- Shorter naps or nap refusal
- Bedtime battles
- Waking too early
- More irritability during the day
When these behaviors start abruptly without illness, sleep regression is usually responsible.
Why Does Sleep Regression Happen at 7 Months?
Rapid Development
Around seven months, babies are learning exciting new skills.
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.
Some babies seek reassurance during night wakings.
Schedule Adjustments
Sleep needs evolve around seven months.
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.
Many babies return to normal sleep within a month.
Stable habits help sleep normalize faster.
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

Predictable routines help babies feel secure.
Short, calming activities prepare babies for sleep.
Adjust Wake Windows
Most babies do best with wake windows useful content of 2.5 to 3 hours.
Encourage Daytime Practice
More playtime can improve nighttime sleep.
Be Consistent With Night Wakings
Gentle reassurance often works best.
Final Thoughts on the 7-Month Sleep Regression
The 7-month sleep regression can be exhausting, but it is temporary.
