Your Fourth Week Home
Your baby's gut is learning. Their brain is growing. Here's what week four looks like from inside the homes we work in.
It’s 3 A.M. and the house is dark except for the soft glow of a nightlight. You’re sitting in the nursery, baby curled against your chest, wondering what happened.
A week ago, things felt different.
Maybe your baby gave you a three-hour stretch of sleep. Maybe feeding started feeling a little more predictable. Maybe you found yourself thinking, Okay. I think we’re getting the hang of this.
And then week four arrived.
Suddenly your baby seems uncomfortable all the time. They’re grunting. Squirming. Pulling their knees up to their chest. Arching their back. Crying when they seemed perfectly content moments before. They look miserable. And if you’re being honest, you’re starting to feel a little miserable too.
You wonder if something is wrong, if you’re missing something, if you’re doing something wrong. You’re not.
Around the one-month mark, most parents become amateur digestive detectives. The late-night searches begin:
“Best gas drops for newborns.”
“How to tell if baby has trapped gas.”
“Should I cut dairy?”
“Best feeding position for gassy babies.”
Soon you’re researching probiotics, gripe water, burping techniques, bicycle legs, tummy massage, and elimination diets. And while some of these tools can certainly help, there’s something important that often gets lost in the search for answers: Almost every baby experiences digestive discomfort. Not because something is wrong. Because their digestive system is brand new.
For nine months, your baby’s nutrition arrived through the placenta. Their digestive tract wasn’t responsible for processing milk, moving gas, coordinating muscles, or learning how to eliminate waste.Now it is. Imagine being handed a complicated piece of machinery and expected to operate it perfectly on day one. That’s essentially what your baby’s body is doing. Their digestive system is learning in real time.
Gassiness often peaks around six weeks of age and gradually improves over the following months as the digestive system matures. Most babies experience significant improvement between four and six months.
Which means this isn’t necessarily a problem to solve. It’s a system coming online. In fact, what you’re experiencing is one of the most common and misunderstood phases of early parenthood. But gas is only part of what is happening...
There’s another piece of the puzzle that many parents find incredibly reassuring. You may have heard of The Wonder Weeks, a framework developed by Dutch researchers that tracks predictable periods of rapid mental development during a baby’s first months and years.
The basic idea is simple: As babies experience major developmental leaps, they often become fussier, clingier, and less predictable. Not because something is wrong, but because something is happening. The first major leap typically occurs around weeks four to six, based on baby’s due date, and is called The World of Sensations. During this period, your baby’s brain begins processing the world in an entirely new way.
Sounds seem louder.
Lights seem brighter.
Patterns become more noticeable.
Touch feels different.
The world suddenly becomes richer, more complex, and more stimulating.
Imagine waking up tomorrow with every sound amplified and every visual detail turned up several notches.
You’d probably feel overwhelmed too.
Many parents notice their baby wants to be held constantly during this phase. Sleep shifts. Fussiness increases. Tears come more easily. What can feel like regression is often growth. The challenging part is that developmental leaps don’t announce themselves beforehand. You don’t get a notification saying, “Your baby’s brain is expanding today. Expect turbulence.” You just find yourself in the middle of a difficult week wondering what changed. Sometimes the answer is simply, your baby is growing.
What Our Doulas See in the Homes That Navigate This Well
After supporting hundreds of families through the fourth trimester, we’ve noticed something interesting. The families who navigate week four with the most confidence aren’t necessarily the ones with the easiest babies, they’re the ones with the most context. They understand that infant gas is usually part of the developmental process. They learn gentle comfort measures like tummy time, bicycle legs, warm cuddles, and skin-to-skin contact. But they don’t become consumed by fixing it. They understand that fussiness can be a sign of development rather than dysfunction.
They stop asking, “How do I make this phase disappear?”
And start asking, “How do I support my baby through it?”
That’s a very different mindset.
One creates panic.
The other creates partnership.
Most importantly, these families aren’t trying to white-knuckle their way through it alone.
The Part We Don’t Talk About Enough
None of this perspective matters if you’re completely depleted. It’s difficult to remember that fussiness is normal when you’ve slept three fragmented hours in two days. It’s difficult to stay calm when your nervous system is running on fumes. That’s why the families who navigate week four best usually have something else in common:
Mom isn’t carrying everything herself.
Maybe her partner takes a full shift so she can sleep.
Maybe a grandparent comes over so she can shower and eat a meal with both hands.
Maybe a postpartum doula takes over the night so she can experience uninterrupted rest for the first time in weeks.
Maybe she simply gives herself permission to step outside for twenty minutes and breathe.
Support doesn’t make you weak. Support makes you sustainable. And a regulated mother is one of the greatest gifts a fussy baby can receive. Your baby doesn’t need perfection. They need a caregiver whose cup isn’t completely empty.
Week four is hard. Not because something is wrong, because everything is right on schedule. Your baby’s gut is learning how to work. Your baby’s brain is expanding. Your family is adjusting to a world that no longer resembles the womb. The families who emerge from this phase feeling more confident aren’t necessarily the ones who found the perfect gas remedy or discovered some secret parenting hack. They’re the ones who had context. The ones who had company. The ones who allowed themselves to rest.
Because sometimes the most powerful thing you can hear at 3 A.M. is this: Your baby is growing, you’re not failing, and you don’t have to do this alone.
Week five brings its own shift. We will be in that room too.
