It is 2 a.m. You have checked the diaper, offered the bottle, walked the hallway for the hundredth time, and your baby is still crying, and underneath the exhaustion a quieter question surfaces: what am I doing wrong? Here is what almost no one says out loud in the hospital. Infant crying climbs along a predictable curve, peaks at around six weeks of age, and settles by three to four months, in babies who are completely healthy and parents who are doing everything right. Researchers have traced that same curve across cultures and caregiving styles. The crying is not a report card on you. It is a stage of development your baby is moving through, out loud, and you are not failing it.
Common questions from parents
Why does my newborn cry so much even when nothing seems wrong?
What are the 5 S’s for soothing a baby?
Is it safe to put my baby on their side or stomach to calm them?
Will responding to every cry spoil my baby?
Newborn crying peaks near six weeks and eases by three to four months in healthy babies. It is not a verdict on your parenting. The 5 S's give you something to do while the stage passes.
The infographic decoded: the 5 S’s and three comfort checks
The five techniques on this infographic come from pediatrician Dr. Harvey Karp, who grouped them as the ‘5 S’s’ because each one recreates a sensation your baby knew for nine months inside the womb. The idea is that familiar input helps settle a newborn’s nervous system. Here is the whole method in plain language, with the safety notes the image keeps small.
- Swaddle: wrap your baby snugly to recreate the close, contained feeling of the womb. Always place a swaddled baby on the back, and stop swaddling once your baby shows any sign of rolling, usually around two months.
- Side or stomach position: hold your baby on their side or tummy in your arms to calm them. This is a holding position only. For every sleep, your baby goes on the back, on a firm flat surface, every time.
- Shush: a steady rhythmic shushing or white noise mimics the constant whoosh your baby heard before birth. Keep any sound machine low and across the room, not next to the crib.
- Swing: small rhythmic movement gives the vestibular system, your baby’s sense of balance and motion, the gentle input it expects. Support the head and keep the motion tiny.
- Suck: a pacifier or a clean finger triggers a newborn’s natural sucking reflex, which is calming. Offering a pacifier at sleep is linked with lower SIDS risk; if you are breastfeeding, wait until feeding is well established.
The infographic adds three comfort checks for the moments the 5 S’s do not land: confirm your baby is not too warm or too cold, watch for gas or reflux discomfort, and try smaller, more frequent feeds to ease digestion. Run through them before you assume something is wrong.
The crying is not a report card on your parenting. It is a developmental stage your baby is moving through out loud, and it ends.

Why familiar sensations settle a newborn, and what your response is building
A newborn spent nine months in constant motion, wrapped tight, surrounded by the rhythmic sound of blood flow and a heartbeat. Birth ends all of it at once. The 5 S’s work, when they work, because they hand a piece of that world back: the snugness of swaddling, the whoosh of shushing, the sway of gentle movement. Dr. Karp describes this as switching on a baby’s calming reflex; treat that as a useful frame rather than a precise mechanism, because every baby answers a little differently and some nights nothing settles them at all.
Here is the part that reaches past the newborn months. Every time you respond to your baby’s cry, you are doing something neuroscientists call serve and return. Your baby signals, you answer, and that back-and-forth is the raw material the developing brain uses to wire its architecture, according to the Center on the Developing Child at Harvard University. Responsive soothing in infancy lays the groundwork for the focus, memory, and emotional regulation a child draws on years later in a classroom. The same neuroplasticity that lets an older struggling reader build new pathways starts here, in the earliest exchanges between you and your child.
Which means the oldest worry handed to new parents, that holding and responding will spoil a baby, has it backwards. You do not spoil a newborn by answering them. You teach a brain that the world is safe enough to relax in, and a relaxed brain is a learning brain.
Key takeaways
- The crying curve is normal: Healthy infant crying peaks around six weeks and eases by three to four months, across every culture studied.
- The 5 S's recreate the womb: Swaddling, side or stomach holding, shushing, swinging, and sucking hand back the snug, rhythmic world your baby knew before birth.
- Responding builds the brain: Answering your baby's cries is serve-and-return, the back-and-forth that wires the developing brain, so responsiveness builds learning instead of spoiling.
When a hard-to-soothe baby gets treated like a problem to fix
Somewhere around the six-week peak, a lot of families hear a label. The baby is ‘colicky.’ The crying must be reflux. A medication gets suggested before the normal crying curve is ever mentioned. Some of this is real and worth a pediatrician’s eyes, yet a large share of infant spitting and fussing is ordinary development that resolves on its own. The pattern is familiar to any parent of an older struggling learner: the system reaches for a diagnosis and a fix faster than it explains what is typical. A baby who cries hard is not a broken baby, and a parent who is unable to soothe every cry is not a broken parent.
That reframe is the whole point of these five techniques. They are not a cure, because healthy crying was never a disease. They are tools that give you something to do with your hands and your baby’s nervous system while a normal, temporary stage runs its course. If you want the broader science on how early experience shapes the learning brain, our companion piece on what neuroplasticity means for a struggling learner picks up exactly where this one leaves off.

This pattern occurs in infants across cultures, whether or not anything is wrong.” Period of PURPLE Crying program, National Center on Shaken Baby Syndrome, drawing on the research of Dr. Ronald Barr

The instinct that wakes you at 2 a.m. and walks the hallway is not something to apologize for. It is the most important early-warning system your child will ever have, and it is already working. Nobody will advocate for your child as hard as you will, and that starts now, with a cry you choose to answer instead of wait out.
The newborn fog lifts, and the questions change rather than disappear: is this milestone on track, why is bedtime a battle, is this struggle normal. Learning Success was built to put real answers and parent-tested tools in your hands at every one of those stages, not a label and a shrug.
When the worries grow up alongside your child, our All Access membership gives you the whole library of courses and screening tools in one place, so you are never again left guessing what to do next.

Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
