Your newborn cries a lot because crying is their only way to communicate, and most of the time, it’s completely normal. Newborns cry an average of about two hours a day, peaking at roughly two hours and six minutes around five to six weeks of age. That number can feel relentless when you’re living through it, but the vast majority of newborn crying follows a predictable biological pattern that resolves on its own by three to four months.
Understanding what drives all that crying can help you respond more effectively and, just as importantly, worry less.
The Normal Crying Curve
Newborn crying isn’t random. It follows a well-documented pattern researchers call the “cry curve.” Crying gradually increases during the first few weeks of life, hits a peak somewhere between four and six weeks, then steadily declines. A large meta-analysis pooling data across multiple countries found that crying and fussing averaged about 126 minutes per day at the five-to-six-week peak. Some evidence suggests the true peak may arrive slightly earlier, around four weeks, before beginning a slow tapering.
After the peak, crying drops off. By about eight weeks, most babies shift into a declining pattern. By three to five months, the intense crying phase is largely behind you. This timeline holds true regardless of whether a baby is breastfed or formula-fed, and it appears across cultures worldwide.
What PURPLE Crying Means
If your baby’s crying seems extreme, unpredictable, and impossible to stop, you may be in what experts call the Period of PURPLE Crying. This isn’t a medical condition. It’s a normal developmental phase. The acronym describes what to expect:
- Peak pattern: Crying increases week over week, peaking around month two.
- Unexpected: Crying episodes come and go with no obvious trigger.
- Resists soothing: Nothing you do seems to help, and that’s not your fault.
- Pain-like face: Your baby may look like they’re in pain even when nothing is wrong.
- Long-lasting: Some babies cry five hours a day or more during this phase.
- Evening: Crying tends to cluster in the late afternoon and evening hours.
Knowing this pattern exists can be a genuine relief. The pain-like expression is especially misleading. Parents naturally assume something is wrong when their baby’s face is scrunched and red, but during PURPLE crying, the expression doesn’t reflect an underlying problem.
Common Reasons Your Newborn Is Crying
Hunger
Crying is actually a late sign of hunger, not an early one. Before your baby cries from hunger, they’ll show subtler cues: putting hands to their mouth, turning their head toward your breast or a bottle, smacking or licking their lips, and clenching their fists. Catching these signals early matters, because a baby who’s been crying from hunger for several minutes will gulp frantically when they finally eat, swallowing extra air that creates even more discomfort afterward.
Gas and Digestive Discomfort
Newborns have immature digestive systems, and passing gas can be genuinely difficult for them. You’ll see it: they ball up, grunt, turn red, wake from a sound sleep, or scream until they produce an impressively loud burp or pass gas. This straining and crying looks alarming, but it’s typically harmless and doesn’t mean your baby has a belly problem or a milk intolerance. Starting feedings before your baby has been crying for a long time helps, since crying itself causes them to swallow air, which creates more gas in a frustrating cycle.
Overstimulation
Newborns have a very low threshold for sensory input. A noisy room, bright lights, being passed between visitors, or even too much playful interaction can push them past their limit. The signs look different from hunger: your baby will turn their head away as if upset, make jerky movements, clench their fists, and wave their arms and legs. They become harder to distract or please. The fix is simple but counterintuitive for well-meaning families. Move to a dim, quiet room and reduce stimulation rather than adding more bouncing, shushing, or rocking.
Evening Fussiness and Cluster Feeding
Many newborns have a “witching hour” in the late afternoon or evening when they’re fussier and want to feed constantly. Some babies want to nurse every 30 minutes during this window. This cluster feeding is normal and doesn’t mean your milk supply is low or that your baby isn’t getting enough. It may be your baby’s way of tanking up before a longer stretch of sleep at night. If you’re breastfeeding, this is one of the most common triggers for unnecessary supplementation with formula, so it helps to know that frequent evening feeding is expected behavior, not a sign of a problem.
When Crying Might Signal Colic
Colic is the label given when a baby’s crying is extreme even by newborn standards. The classic definition, known as the “rule of three,” is crying more than three hours per day, more than three days per week, for longer than three weeks. Colic is considered a benign process, meaning it doesn’t cause lasting harm to your baby, but it can be deeply distressing for parents.
Colic follows the same general timeline as the PURPLE crying curve, typically appearing in the first few weeks and resolving by three to four months. There’s no single proven cause. The important thing to know is that colic is a pattern of excessive but normal developmental crying, not a disease. If your baby is gaining weight normally, feeding well, and has no other symptoms, intense crying alone usually falls into this category.
Reflux: Normal Spitting vs. Something More
Most newborns spit up. That’s ordinary gastroesophageal reflux, and it doesn’t bother them. Babies with normal reflux gain weight fine, feed without trouble, and seem generally unbothered by the spitting. They’re sometimes called “happy spitters.”
Reflux becomes a concern when it crosses into disease territory. The warning signs include forceful vomiting, crying or arching the back during feedings, refusing to eat, poor weight gain, vomiting blood, wheezing, or noisy breathing. If your baby seems distressed during or after every feeding and isn’t growing as expected, that’s worth a conversation with your pediatrician. The key distinction is whether the spitting is affecting your baby’s comfort and growth, or just creating extra laundry.
Soothing Techniques That Help
No single technique works for every baby, and during the PURPLE crying phase, nothing may work at all. That said, several approaches are worth trying:
Swaddling can help some newborns feel secure. Keep the swaddle snug but not tight, make sure your baby’s hips can move freely, and always place them on their back. Once your baby shows any signs of trying to roll over, stop swaddling immediately.
Gentle rhythmic motion, like rocking or swaying, mimics the movement babies experienced in the womb. White noise works on a similar principle. Skin-to-skin contact is one of the most consistently calming interventions. Offering a feeding is always reasonable if it’s been an hour or two since the last one, even if your baby doesn’t seem to show classic hunger cues.
When you’ve cycled through everything and your baby is still crying, it’s okay to place them safely on their back in the crib and step away for a few minutes. A short break protects your ability to keep responding with patience.
Red Flags That Need Immediate Attention
Most crying is normal, but certain symptoms alongside crying require urgent medical evaluation. For any baby under one month old, a fever or looking sick in any way (vomiting, cough, poor color) is reason to call your doctor right away. For babies under three months, a rectal or forehead temperature of 100.4°F or higher needs prompt attention.
Bright green vomit is a specific emergency sign. Unless your baby drank something green, green vomit can indicate a bowel obstruction that requires surgical evaluation. Other red flags include a sudden change in the character of crying (a high-pitched, unusual-sounding cry), a bulging soft spot on the head, blood in the stool, or a baby who is limp and difficult to wake between crying episodes.
If your baby is crying intensely but feeding well, gaining weight, having normal wet and dirty diapers, and calming at least some of the time, you’re very likely dealing with the normal, temporary, and deeply exhausting reality of early infancy.
