How to Get a 6-Month-Old to Sleep Through the Night
Getting your 6-month-old to sleep through the night feels like chasing a moving target. One week they’re sleeping beautifully, the next they’re up every two hours. If you’re reading this at 3 AM with a crying baby, take heart—you’re not alone, and there are proven strategies that work.
Why Your 6-Month-Old Struggles with Nighttime Sleep
At six months, your baby’s world is exploding with new discoveries. They’re learning to sit up, maybe starting to crawl, and their brain is processing an incredible amount of information daily. This developmental leap often disrupts sleep patterns, creating what many parents experience as the 6-month sleep regression.
Your baby’s sleep needs are also evolving. Most 6-month-olds require 14-15 hours of total sleep in a 24-hour period, with 10-12 hours ideally happening at night. However, their natural sleep cycles are still maturing, making those coveted 8-hour stretches challenging to achieve consistently.
The Science Behind Baby Sleep Patterns
Unlike adults who cycle through sleep stages every 90-120 minutes, babies have shorter sleep cycles of about 50-60 minutes. During these transitions between light and deep sleep, they’re more likely to wake up. This is actually a protective mechanism—babies need to be able to wake easily if they’re uncomfortable, hungry, or in distress.
Dr. Sarah Mitchell, a pediatric sleep consultant, explains that around 6 months, babies develop stronger circadian rhythms. This means they’re becoming more aware of day and night patterns, which you can use to your advantage when establishing healthy sleep habits.
Proven Strategies for Longer Night Sleep
1. Master the Bedtime Routine
Consistency is your secret weapon. Start your routine 30-45 minutes before you want your baby asleep. A typical sequence might include:
- Warm bath (not too stimulating)
- Gentle massage with calming lotion
- Quiet feeding in a dimly lit room
- Soft lullabies or white noise
- Placing baby in crib drowsy but awake
The key is doing the same activities in the same order every night. This predictability helps your baby’s brain recognize sleep cues.
2. Optimize Daytime Sleep
Counterintuitively, better daytime naps often lead to better nighttime sleep. Overtired babies actually sleep worse, not better. Use our 6-month-old nap schedule guide to establish age-appropriate wake windows.
For 6-month-olds, aim for:
- 2-3 naps per day
- Wake windows of 2-3 hours between sleep periods
- Total daytime sleep of 3-4 hours
3. Create the Ideal Sleep Environment
Your baby’s room should be a sleep sanctuary:
- Temperature: 68-70°F (20-21°C)
- Darkness: Blackout curtains or shades
- Sound: Consistent white noise at 50 decibels
- Safety: Firm mattress, fitted sheet, nothing else in the crib
Consider using our mattress size calculator to ensure your baby’s sleep surface is appropriate for their age and size.
4. Encourage Self-Soothing Skills
This is often the hardest part for parents, but teaching your baby to fall asleep independently is crucial for sleeping through the night. When they wake during natural sleep transitions, they’ll be able to settle back down without your help.
Start by putting your baby down awake but drowsy. If they cry, wait a few minutes before responding. This doesn’t mean letting them cry indefinitely—it means giving them a chance to learn self-regulation.
Gentle Sleep Training Methods That Work
The Pick-Up-Put-Down Method
When your baby cries, pick them up until they calm down, then put them back in the crib. Repeat as needed. This method takes patience but avoids prolonged crying.
Gradual Extinction (Ferber Method)
Check on your baby at timed intervals (3 minutes, then 5 minutes, then 10 minutes) without picking them up. Offer brief comfort with your voice, then leave again.
Chair Method
Sit in a chair next to your baby’s crib for a few nights, then gradually move the chair farther away until you’re outside the room.
Common Obstacles and Solutions
Sleep Regressions
Just when you think you’ve figured it out, your baby might experience a sleep regression. The 6-month sleep regression is particularly common and can last 2-6 weeks. Stay consistent with your routines—this too shall pass.
Teething Disruptions
Teething pain can definitely disrupt sleep. Our guide on 6-month sleep regression vs. teething helps you identify the difference and respond appropriately.
Growth Spurts
During growth spurts, your baby may genuinely need more frequent feeding. These typically last 2-3 days and then sleep patterns usually return to normal.
When to Seek Professional Help
Consult your pediatrician if:
- Your baby consistently wakes more than 3 times per night after 8 months
- Sleep issues are affecting your baby’s daytime mood and development
- You’re experiencing severe sleep deprivation that’s impacting your mental health
Understanding sleep deprivation effects can help you recognize when professional support is needed.
Building Long-Term Healthy Sleep Habits
Remember that sleep is a learned skill. Just like walking or talking, some babies master it quickly while others need more time and practice. Stay patient and consistent with your approach.
Use tools like our advanced sleep calculator to optimize sleep schedules as your baby grows. Understanding sleep cycles and timing becomes increasingly important as your child develops.
The Bottom Line
Getting your 6-month-old to sleep through the night requires patience, consistency, and the right strategies. Focus on establishing predictable routines, creating an optimal sleep environment, and gradually teaching self-soothing skills.
Every baby is different, so what works for your friend’s child might not work for yours. Trust your instincts, stay consistent with your chosen approach for at least 2-3 weeks before making changes, and remember that this challenging phase is temporary.

Sweet dreams are coming—for both you and your little one.
