Most babies can be calmed by addressing one of a few basic needs: hunger, a dirty diaper, tiredness, gas, or overstimulation. The trick is figuring out which one, and fast. Crying is how babies communicate, and while it can feel overwhelming, a systematic approach works surprisingly well. Start with the most common causes and work your way down.
Check for Hunger First
Hunger is the number one reason babies cry, and by the time they’re actually wailing, they’ve already been signaling for a while. Crying is a late sign of hunger. The earlier cues are subtle: putting hands to their mouth, turning their head toward your breast or a bottle, smacking or licking their lips, and clenching their fists. If you spot these before the crying starts, feeding goes much more smoothly because the baby is still calm enough to latch or take a bottle.
Once a baby is full, the signals flip. They’ll close their mouth, turn away from the breast or bottle, and their hands will relax and open. If you’ve just fed your baby and they’re still crying, hunger probably isn’t the issue. Move on.
Try the Five S’s
Pediatrician Harvey Karp popularized a set of five soothing techniques that mimic the environment of the womb. They work best when layered together rather than tried one at a time:
- Swaddling: Wrap your baby snugly in a blanket with arms tucked in. This reduces the startle reflex that can wake or upset them. Stop swaddling once your baby shows signs of rolling over.
- Side or stomach position: Hold your baby on their side or stomach against your body. This is for soothing only, not for sleep. Always place babies on their backs to sleep.
- Shushing: A loud, steady “shhhh” close to your baby’s ear mimics the whooshing sound of blood flow they heard in the womb. It needs to be at least as loud as the crying to register.
- Swinging: Small, gentle, jiggly movements (supporting the head and neck) can calm a baby quickly. Think of it as a gentle vibration rather than a big rocking motion.
- Sucking: Offer a pacifier, a clean finger, or the breast. Non-nutritive sucking is one of the most powerful calming reflexes newborns have.
Relieve Gas and Tummy Discomfort
A gassy baby often pulls their knees toward their chest, arches their back, or has a hard, bloated belly. If you suspect gas, a few physical techniques can help move things along. Lay your baby on their back and gently bicycle their legs, pushing one knee toward the belly, then the other, in a slow pedaling motion. This puts gentle pressure on the intestines and can release trapped air.
The “football hold” also works well: lay your baby face-down along your forearm with their head near your elbow and your hand supporting their diaper area. The pressure on their belly combined with a gentle bounce can bring relief fast. Tummy time on a flat surface (while supervised and awake) serves a similar purpose. Burping more frequently during feeds, every two to three ounces from a bottle or when switching breasts, can prevent gas from building up in the first place.
Rule Out Overstimulation
Babies have a low threshold for sensory input. A noisy room, bright lights, being passed between relatives, or too much playtime can push them past their limit. An overstimulated baby often turns their head away, avoids eye contact, and may stiffen their body before the crying begins.
The fix is simple: reduce everything. Move to a dim, quiet room. Hold your baby close with minimal bouncing or talking. Skin-to-skin contact, your bare chest against theirs, can be especially effective because it gives them warmth and your heartbeat without any additional stimulation. Sometimes what a baby needs most is less, not more.
Use White Noise Safely
White noise can be remarkably effective because it replicates the constant low roar babies hear inside the womb. A fan, a dedicated sound machine, or even a phone app can work. The key is getting the volume and distance right. Pediatricians recommend keeping white noise at or below 50 decibels, roughly the volume of a quiet conversation, and placing the machine at least 7 feet from your baby’s sleeping space. Louder levels or closer placement can risk hearing damage over time.
White noise works best as a background layer combined with other soothing techniques, not as the sole strategy. Once your baby calms down or falls asleep, you can turn the volume down further or switch it off.
When Nothing Works: The PURPLE Crying Phase
If your baby seems inconsolable for hours despite everything you try, you may be dealing with a normal developmental phase rather than a problem you can solve. The Period of PURPLE Crying typically starts around 2 weeks of age and peaks at about 2 months before tapering off by 3 to 5 months. Each letter in PURPLE describes a feature of this phase:
- Peak of crying that increases week over week before improving
- Unexpected episodes with no apparent trigger
- Resists soothing no matter what you do
- Pain-like face even though nothing is wrong
- Long-lasting bouts that can stretch for hours
- Evening timing, with crying clustering in the late afternoon and night
This phase is not caused by anything you’re doing wrong. It reflects the baby’s developing nervous system and is seen across cultures worldwide. Understanding that it’s temporary and normal doesn’t make it less exhausting, but it can keep you from spiraling into worry that something is medically wrong.
Is It Colic?
Colic is essentially the extreme end of normal infant crying. The standard diagnostic criteria, known as the “rule of three,” defines colic as crying more than three hours per day, more than three days per week, for longer than three weeks. A baby with colic is otherwise healthy, gaining weight, and feeding normally.
There’s no single cure for colic, which is part of what makes it so frustrating. The same soothing techniques listed above are the frontline approach: swaddling, white noise, motion, and gas relief. Some parents find that dietary changes help, particularly if a breastfeeding parent eliminates dairy for a trial period, since cow’s milk protein sensitivity can contribute to fussiness in some infants. Colic almost always resolves on its own by 3 to 4 months of age.
Protect Your Own Composure
Prolonged crying triggers a stress response in adults. Your heart rate goes up, your patience drops, and your ability to think clearly narrows. This is biology, not a character flaw. If you feel yourself reaching a breaking point, it is completely safe to put your baby down in their crib on their back, walk out of the room, and take five minutes to breathe. A baby crying alone in a safe space for a few minutes is in no danger. A frustrated caregiver holding a baby is a risk factor for shaking injuries.
Tag in a partner, family member, or friend when you can. Even 15 to 20 minutes of relief can reset your nervous system enough to try again with a clearer head.
Signs That Crying Needs Medical Attention
Most crying is normal, but certain combinations of symptoms point to something that needs a pediatrician’s evaluation. For babies under 3 months, any fever of 100.4°F or higher warrants an immediate call. For older children, a fever above 104°F that keeps returning is a red flag regardless of age.
Beyond fever, contact your pediatrician if your baby looks unusually drowsy or limp, has a stiff neck, develops an unexplained rash, is vomiting or having diarrhea repeatedly, has difficulty breathing, or simply “acts sick” even after a fever comes down. A fever lasting more than 24 hours in a child under 2, or more than 72 hours in an older child, also warrants a call. Trust your instincts here. You know your baby’s baseline, and a significant departure from it is worth a phone call even if you can’t pinpoint exactly what’s different.
