You have probably heard of sleep regressions. Four months, eight months, twelve months. They are often spoken about as something you just have to survive.
But what is actually happening?
A sleep regression is usually a period of rapid development. Your baby’s brain is maturing, their sleep cycles are changing, and they are becoming more aware of the world around them.
This can lead to more night waking, shorter naps, and difficulty settling.
The four month regression is the most significant. This is when sleep becomes more like an adult pattern, with lighter and deeper stages.
From this point on, how your baby falls asleep really matters.
If they rely heavily on help to fall asleep, they will often need that same help each time they transition between sleep cycles.
Other regressions are often linked to mobility, separation awareness, or big developmental leaps.
The key thing to know is that regressions are temporary, but habits can stay.
This is why many families choose to gently support more independent sleep during or after these phases.
With the right guidance, these periods do not have to feel chaotic.
