Parents: New research claims that infant crying does not peak after 6 weeks, but it's apparent that they have a reason to stay afloat

If you''re a parent, you may well be familiar with the internet, where you may find answers for everything from sleep patterns to weird rashes, and one of the questions you might have answered through a search engine is, "When do babies stop crying so much?"

Up until now, the most authoritative study on the topic from 1962 suggested that crying peaks at 6 weeks, before tailing off and stabilizing at a low level after 12 weeks the generally accepted "cry curve."

A new study, which includes a greater amount of data collected over a longer period, shows that sustained crying in infants can last much longer, and the company behind the program wants to redraw the crying curve.

"If you Google ''infant crying,'' says an Arnault-Quentin Vermilletan instructor in cognitive science at Aarhus University in Denmark.

"For us, we thought it would be useful to model all the available data to determine what type of pattern best represents the data, and to see if this is consistent with the original''cry curve."

Overriding (colic) is expected to be crying for more than three hours per day and at least three days per week in the first six weeks after birth. Between 17 and 25 percent of babies are believed to be colic.

The group compiled data from 17 different nations and 57 separate research projects, covering crying habits for a total of 7,580 infants, as reported by their parents. Despite the fact, the data spanned 12 months rather than 12 weeks that the 1962 study centered.

While the findings indicated a lot of variation in terms of crying patterns, the researchers rounded the numbers to develop two statistical models: one showing a crying peak after four weeks, and another showing a steady level of crying for the first weeks, followed by a gradual decrease.

Both models operate well with the traditionally accepted cry curve, while data also suggests that excessive crying can often continue for months, which might be reassuring for new parents to be curious about their babies.

"We''ve created two mathematical models that are suitable to the needs of the individual," Christine Parsons of Aarhus University said.

"Neither of them show that the duration of crying drops so dramatically after five weeks, which is what they otherwise see in the screens that are presented to parents. According to the previous research, crying remains a significant part of many infants'' repertoire after six months."

The researchers observed that crying habits vary quite widely between countries, although data is limited in some regions. In India, Mexico, and South Korea, infant sobbing rates are lower than in countries such as the United States, Great Britain, and Canada.

Crying is an important component of a child''s development. It''s used to attract attention of parents, and how they react may be beneficial in terms of the infant''s cognitive and emotional development.

As well as reassuring parents about what the norms in terms of crying patterns, the new research may be beneficial to healthcare professionals who are tasked with discovering when something more serious might be.

"For clinicians in particular, it''s vital because their objective is to assist, assist, and reconcile the expectations of any concerned parents," Parsons said.

"It''s very important that clinicians have up-to-date statistics on what is normal for infant crying, so that they can best assist new parents."

The research has been published in Child Development.
