What are sleep transitions (or regressions) and how to survive them?

If you feel like you were finally starting to get the hang of this whole “parenting” thing, and then suddenly... bam! Your baby starts waking up every hour, you’ve probably hit the dreaded “sleep regression" (that I actually like to call sleep transition since it's part of the development and not a real regression). Don’t panic. While it feels like a major setback, these sleep transitions are actually a sign that your little one’s brain is doing some pretty amazing work.

What is a Sleep Regression, Anyway?

Think of it as a developmental growth spurt for your baby’s brain. When they are newborns, their sleep is pretty simple: it’s either light sleep or deep sleep, and they move between them pretty easily. Their sleep cycles are short, about 40–50 minutes long.

But around that 3.5 to 4-month mark, something big happens. Their sleep matures. It starts to look more like yours, with different stages including deep sleep and REM (the dream-filled kind). The problem? They haven’t quite figured out how to move from one cycle to the next on their own yet. So, when they hit that gap between cycles, they wake up completely, and they need a little help to drift back off.

Why Do They Happen?

It’s not just about sleep cycles. Sleep transitions (regressions) often happen when your baby is hitting big milestones—like learning to roll over, sit up, or even just becoming more aware of the world around them. Their brains are so busy practicing these new skills that it’s hard for them to shut down at night. It’s like trying to sleep when you are on vacation and have so many exciting things to do that is hard to relax.

What to do when sleep patterns change?

Understanding why sleep regressions happen is the first step toward maintaining your sanity. It is an incredible developmental milestone, but the transition from a simple sleep cycle to a complex one. similar to our own, is undoubtedly the moment that disrupts sleep the most in the first few months.  

The big question isn't just knowing why it happens, but having a clear plan to navigate this change without exhaustion. Many families try quick fix methods that end up causing more confusion, when, in fact, what the baby needs is a structure that respects their development and helps with this transition in a gentle way.  

If you are exhausted from trying to guess what works and feel like you need a real, step-by-step plan that is tested and adapted to your baby's rhythm, I have been preparing something specific for this. So stay tuned for the release of my course. I will teach you exactly how to create a solid routine, help your baby connect sleep cycles, and restore predictability (and rest!) to your home.
