"Is there a 6 month sleep regression?"

Your baby was finally sleeping well, and suddenly everything has changed OR, sleep started to get messy at 4 months, and now it is a hot steaming mess....
If you're wondering whether the 6-month sleep regression is real – and more importantly, how to survive it – you're in the right place.
What's Really Happening at 6 Months?
The term "sleep regression" can be misleading. What's actually occurring around 6 months is a perfect storm of developmental milestones:
Physical developments (rolling, sitting, maybe even crawling)
Cognitive leaps (increased awareness of surroundings, more sociable)
Changes in sleep cycles (becoming more adult-like)
Potential introduction of solid foods
Why Sleep Changes at This Age
Here's what many parents don't realize: at 4 months, your baby's sleep becomes biological, not logical. Their body starts following natural sleep rhythms, regulated by sleep hormones like melatonin and adenosine. When these hormones peak at specific times during the day, it creates optimal "sleep windows" for rest.
In other words, it's time to throw wake windows out the window...
Signs Your 6-Month-Old is Experiencing Sleep Changes
Fighting naps they previously took easily
Waking more frequently at night
Difficulty falling asleep at bedtime
Short naps (30-45 minutes)
Early morning wakings
The Science Behind Better Sleep
Rather than focusing on strict wake windows, success comes from working with your baby's natural sleep rhythm. When we miss these biological sleep windows, our little ones become overtired, triggering stress hormones like cortisol and adrenaline – making it even harder for them to sleep!
How to Navigate This Phase
Stick to Biological Sleep Windows
First nap start time: 9:00-9:30 AM
Second nap start time: 12:00-1:30 PM
Bedtime: Align with their natural sleep pressure (typically 7:00-7:30 PM)
Early bedtime: If naps were short that day and baby is very overtired, bring bedtime as early as 6:00/6:30 PM to prevent their stress hormones from spiking
Optimize the Sleep Environment
Keep the room boring and free from distractions
Use appropriate sleep clothing (consider a 4-season sleep sack)
Effectively blackout baby's room; this is particularly game changing for lengthening naps, and successful bedtimes during the Summer months
Maintain Consistency Think of it like starting a new workout regime – consistency is key. Following your sleep plan "ish" will only get you results "ish"!
Once your baby's sleep becomes more restorative and predictable, they will be much more flexible, and can adjust the occasional later bedtime or nap on the go, without becoming overtired
"Think of it like helping your baby learn to walk: at first, you offer lots of support, then slowly step back as they gain confidence in this new skill"
Understanding Independent Sleep
Let's talk about the elephant in the room: sleep training. This term often strikes fear in parents' hearts, but it shouldn't! At its core, sleep training is simply the process of supporting your baby in learning to fall asleep independently – a skill that's developmentally appropriate for most 6-month-olds.
What Does "Independent Sleep" Really Mean?
"Independent sleep" basically means your baby falling asleep on their back, in their crib, without being held/rocked/fed to sleep, and then being transferred to the crib.
Why is this important? If your baby can fall asleep independently, they will seamlessly connect their sleep cycles during naps and nighttime sleep - which equals naps lasting 1-2 hours, and 10-12 hours of consolidated nighttime sleep!
Think of it like teaching your little one to walk. At first, you provide lots of support, then gradually step back as they gain confidence. Sleep independence works the same way. It's not about abandoning your baby to "figure it out" – it's about giving them the opportunity to develop this essential life skill while providing appropriate support.
The Sleep Training Spectrum
Sleep training isn't one-size-fits-all. Instead, think of it as a sliding scale of methods:
High-Contact Methods
Parent stays in the room
Offers consistent physical and verbal reassurance
Perfect for anxious children or those transitioning from co-sleeping
Moderate Approaches
Gradual reduction in physical presence
Scheduled check-ins and comfort
Balances support with independence
Low-Involvement Methods
More space for independent settling
Brief, purposeful parent interactions
Often leads to faster results
All these approaches can be effective and safe when implemented correctly with professional guidance. The key is choosing a method that aligns with your parenting style and your baby's temperament.
Setting Up for Success
Before beginning any sleep training method:
Ensure your baby's sleep environment is optimal
Start when they're healthy, with no residual cold/sickness/congestion etc
Choose a time when you can be consistent for at least a week
Remember that some protest is normal as your baby learns this new skill
The Good News
Outside of underlying health conditions that could be disruptive for sleep, the average 6 month old is biologically capable of sleeping through the night!
Night feeds at this age are still common, with most babies needing 1 night feed at the 6 month stage, with baby effortlessly returning to sleep after taking on necessary calories.
When to Seek Help
If you've been struggling with sleep challenges for weeks or months, know that you don't have to figure this out alone. A customized sleep plan, tailored to your baby's unique needs and personality, can transform those frustrating nights into peaceful sleep – while maintaining a loving, supportive presence throughout the process.
Remember, this phase is temporary, and with consistent, gentle guidance, your little one can learn to sleep soundly again. The key is working with their natural sleep rhythms while providing the support they need during this significant developmental period.
