Most fussy babies respond to a combination of gentle movement, sound, and physical closeness that mimics what they experienced in the womb. Fussiness peaks around the second month of life and typically tapers off by month five, so if you’re in the thick of it, there is a predictable end point. Here’s what actually works and how to figure out what your baby needs.
Why Babies Have a Fussy Period
Infant fussiness follows a well-documented pattern sometimes called the PURPLE crying period. It usually starts around two weeks of age, peaks during the second month, and fades by three to five months. During this stretch, it’s not uncommon for babies to cry five hours a day or longer, often in the late afternoon and evening, with no clear cause. This isn’t a sign that something is wrong with your baby or that you’re doing something incorrectly. It’s a normal developmental phase tied to a still-maturing nervous system.
That said, not all fussiness is the same. Before cycling through soothing techniques, it helps to narrow down what your baby is actually telling you.
Reading Your Baby’s Cues
A hungry baby and an overstimulated baby look different if you know what to watch for. Hunger cues tend to appear alongside calm, open body language: rooting (turning toward your hand or chest with an open mouth), smooth body movements, and alert eyes that track your face. These are engagement signals, meaning your baby is reaching out for something.
Overstimulation and tiredness produce the opposite pattern. Your baby may turn or look away from you, yawn repeatedly, get a glazed or unfocused look, or arch their back and push away. Stiff, splayed fingers are another common sign of sensory overload. If you see these disengagement cues, your baby likely needs less input, not more. Dimming lights, reducing noise, and moving to a quieter room can do more than any bouncing or shushing in that moment.
Other common triggers worth ruling out quickly: a wet or dirty diaper, clothing that’s too warm or too cool, and gas pain (more on relieving that below).
The 5 S’s Technique
The most widely recommended soothing framework is a set of five steps, each designed to recreate conditions from the womb. You don’t have to use all five at once. Start with one or two and layer on more if your baby doesn’t settle.
- Swaddling. Wrapping your baby snugly in a blanket provides warmth and the gentle pressure they felt in utero. Keep the swaddle firm around the arms but loose enough at the hips that your baby’s legs can bend and move freely. Always place a swaddled baby on their back, and stop swaddling once your baby shows any signs of trying to roll over.
- Side or stomach position (while held). Holding your baby on their side or belly against your chest or forearm can calm them when lying on their back doesn’t. This is strictly a holding position, not a sleep position. Babies should always sleep on their backs.
- Shushing. A sustained “shhhh” sound near your baby’s ear imitates the noise of blood flowing through the placenta, which was a constant backdrop in the womb. You can also use a white noise machine, but keep the volume below 50 decibels (about the level of a quiet conversation) and place it at least two feet from the crib.
- Swinging or swaying. Small, rhythmic movements replicate the motion your baby felt when you walked during pregnancy. Gentle rocking in your arms, a baby swing, or slow swaying side to side all work. The key is keeping the movements small and controlled, supporting the head and neck at all times.
- Sucking. Non-nutritive sucking on a pacifier or clean finger activates a calming reflex. This can be especially effective after a feeding when your baby is full but still unsettled.
Combining two or three of these simultaneously, like swaddling plus shushing plus gentle rocking, is often more effective than any single technique alone.
Skin-to-Skin Contact
Holding your baby against your bare chest is one of the simplest and most powerful calming tools available. Research consistently shows that skin-to-skin contact lowers an infant’s heart rate, steadies their breathing, and reduces levels of cortisol, the body’s primary stress hormone. Babies who are held skin-to-skin show measurably better physiological stability than those who aren’t, and the effect works for both mothers and fathers.
The mechanism is straightforward: your body temperature, heartbeat, and breathing rhythm act as external regulators for your baby’s still-developing nervous system. If your baby is fussy and you’ve checked the obvious causes, try stripping them down to a diaper, removing your shirt, and holding them upright against your chest with a light blanket draped over both of you. Give it at least 10 to 15 minutes. Many babies settle within that window.
Relieving Gas Discomfort
Gas is one of the most common physical causes of fussiness, especially in the first few months when your baby’s digestive system is still maturing. Signs include a hard or bloated belly, pulling the legs up toward the chest, and crying that seems to come in waves.
A simple technique that works well: lay your baby on their back, hold one leg in each hand, and gently move their legs in a slow bicycling motion. After several seconds of bicycling, press both knees gently back toward their belly to help push trapped gas out. You can repeat this several times throughout the day.
Tummy time while your baby is awake and supervised also puts gentle pressure on the abdomen that can help move gas along. If your baby is bottle-fed, paced feeding (holding the bottle more horizontally and letting your baby take breaks) can reduce the amount of air swallowed during meals. Studies show this approach slows feeding rates and extends meal duration without reducing how much milk your baby takes in, giving their stomach time to process each swallow.
Feeding-Related Fussiness
Babies who seem fussy during or right after feeding may be dealing with something other than hunger. Eating too fast, swallowing air, or being fed past fullness can all cause discomfort. If your baby pulls away from the breast or bottle, arches their back, or seems agitated mid-feed, try pausing for a burp before continuing.
For breastfed babies, a forceful letdown (when milk flows too fast at the start of a feeding) can overwhelm a newborn. Feeding in a more upright or reclined position, where your baby is above the breast rather than below it, lets gravity slow the flow. For bottle-fed babies, paced feeding is especially useful. Instead of letting your baby drain the bottle in one continuous effort, tip the bottle down every minute or so to give them a natural break, mimicking the rhythm of breastfeeding.
When Fussiness Signals Something More
Pediatricians define colic using the “rule of threes”: crying for more than three hours a day, more than three days a week, for at least three weeks in an otherwise healthy baby. Colic is not dangerous, but it is exhausting, and it’s worth mentioning to your pediatrician so they can rule out underlying causes and connect you with support.
Certain symptoms alongside fussiness do warrant a call to your baby’s doctor. A fever in any baby younger than three months needs immediate medical attention, regardless of how high it is. For babies three to six months old, a temperature of 100.4°F or higher paired with any sign of illness is worth a call. Vomiting that shoots out forcefully (as opposed to normal spit-up that dribbles), inability to keep liquids down for eight hours, and unusual sleepiness or floppiness are all red flags. A baby who is significantly harder to calm than usual, seems sluggish, or is vomiting repeatedly should be seen urgently.
Trust your instincts on this. You know your baby’s baseline better than anyone, and a change in the quality or pattern of their crying, not just the amount, is meaningful information.
