Today we will share with you a brief intro of the 4-month sleep regression. So buckle up to learn lots of new things that will later help you and the baby.

Without further ado, let’s take a quick look!

What is Sleep Regression Anyway?

Sleep regression is simply a pain either in babies or adults. But things get out of hand when the baby is only 4-months old. And the worst part is your baby can’t tell you a single thing. Being a parent it is your responsibility to understand and take care of your child.

The term refers to a disturbance or disruption in the sleep cycle for more than a few days. Now, it often happens with the adults also, the normal cycle flips completely. And the result is sudden tension, a frustration that you can’t get over with.

This phenomenon is more common in babies, especially when they reach 4-months. Then it keeps on coming back around 8 months, then at 12 months and even at 18 months.

What is the Four-Month Sleep Regression?

Coming towards the particular phase of sleep regression; 4-month. This is something that every parent has to face at least once in a lifetime. So rather than stressing over and crying out loud, learn a bit about it.

Once your baby is over 3-4 months old, they become light sleepers. You might notice that before this age, your baby slept throughout the day. But that suddenly came to a halt because your baby is now growing.

Their minds are now growing and they tend to notice the surroundings. So this little yet curious and active brain keeps them awake. And the result is sleep regression that is every parent’s worst nightmare.

Clear Signs of 4-month Sleep Regression

Here are a few of the most common and basic signs of sleep regression. Sometimes the child is actually sick or growing teeth but parents misinterpret it. So these causes/signals will help you to differentiate well.

Increased Fussiness

Babies will be fussier usually as it is not something they can control. For them throwing tantrums and fuss is the only way to express any emotion.

But there has to be a certain level to the fuss they create. A sudden increase in this a direct hint of sleep regression. Or if the fuss starts when it is bed-time, take the hint.

Napping Longer

When the regression occurs, your baby won’t get any sleep at night. Ultimately they feel tired throughout the day and either keep on sleeping now and then. Or they would take a long nap during the day. Hence such a scenario hints towards sleep regression but it can be part of the growth also.

Frequent Nighttime Waking

Every baby wakes up at night at least one time, if not for a diaper change then for feeding. But in case the waking up exceeds the limit (twice), it is sleep regression. In fact, nighttime waking is the most common sign in any baby. They would wake up during the nights and won’t go back to sleep easily.

Change in Appetite

At an age of 4 months, your baby either takes breast milk or baby formula. This is the only source of fulfilling the appetite for the little one. But even if your baby seems to refuse this or spit the milk or intake more than usual. These sudden changes are a clear signal that regression has started.


Your baby will also be restless even if sleeping at night. They would cry a lot, won’t be easy to console, and whatnot. You might want to cry out at some point but hold on. Being a parent is an experience that brings challenges along with sweet moments. So all you need to do is buckle up for your little ones and help them to get through the regression phase.
