If you’re a new parent who has frantically searched, “Why is my baby crying?” rest assured you’re not alone. Recent surveys indicate that 38% of parents do the same during their child’s first year. And if you’ve found yourself wondering how long this will continue, you’re in good company. Many exhausted parents have held a wailing infant in one arm while using the other to scroll for reassurance that their baby’s cries won’t last forever.
Traditionally, most of these inquiries have pointed parents toward the ‘cry curve’ theory. This concept, derived from a 1962 U.S. study, presents a bell-shaped graph suggesting that infant crying peaks around 6 weeks of age before gradually decreasing to a manageable level by 3 months. This curve implies a natural transition from a calm newborn to a fussy infant, offering hope that relief is on the horizon. However, a recent study from Aarhus University in Denmark challenges this long-held belief. Researchers analyzed 57 studies about infant crying from 17 different countries and found that the data does not conform to the ‘cry curve’ or any single pattern.
The researchers developed two new models: one indicating that crying peaks after 4 weeks, and another suggesting that while crying is high in the early weeks, the decline is not as steep or comforting as previously thought. “Our two mathematical models accurately reflect the data we examined. Neither demonstrates such a significant drop in crying duration after five weeks, which contrasts with the graphs typically shared with parents. The data shows that crying remains a substantial part of many infants’ behavior even after six months,” stated Alex Thompson, an associate professor at Aarhus University.
Interestingly, the study also found considerable variations in crying patterns among infants from different countries. Babies in the U.S., Great Britain, and Canada reportedly cry more than their counterparts in Mexico, India, and South Korea.
So, if your baby continues to cry consistently after six weeks, take heart—it’s not unusual, and you are definitely not alone. Colic, defined as crying for over three hours a day, more than three days a week, affects an estimated 17-25% of babies. Unfortunately, the conventional ‘cry curve’ may not apply to your little one, making it difficult to predict when the crying will cease. But rest assured, it will eventually come to an end. And one day, as your teenager articulates their frustrations with eloquence, you may even find yourself reminiscing about the days of infant cries.

Summary
A recent analysis from Aarhus University questions the traditional ‘cry curve’ theory, revealing that infant crying patterns do not conform to a single peak and decline. Instead, crying may remain significant beyond the six-week mark, varying by country and individual baby. While this may be disheartening for parents seeking reassurance, it’s important to know that prolonged crying is not unusual and will eventually subside.
