Does your baby cry no:
Soothing an crying infant is one of the most trying trials of parenting. Nevertheless, Despite attentive care. Therefore, a well -established routine, and all the techniques recommended by experts, some babies continue to cry – sometimes for a long time, often without clear explanation. Furthermore, A new Swedish study finally sheds light on this mystery which disturbs so many young parents: the tendency to. Consequently, cry would be largely inscribed in the genes.
Cry. Therefore, a trait inherited more than acquired – Does your baby cry no
This is revealed by a team of researchers from the University of Uppsala and the Karolinska Institute, which conducted a large -scale study on more than 1,000 twins aged two to five months. Nevertheless, By comparing the behavior of identical (sharing 100 % DNA). In addition, fraternal (sharing around 50 %) twins, scientists were able to distinguish the does your baby cry no impact of genetics compared to that of the family environment.
The results. Moreover, published in the journal JCPP Advancesare final: genetics explains about Half of the frequency of crying in two -month -old babiesand until 70 % to five months. For example, In other words. Therefore, some infants are simply born with a greater propensity to cry, regardless of the quality of the parental environment.
Relief for parents – Does your baby cry no
For Charlotte Viktorsson. postdoctoral researcher in psychology and the main author of the study, these results can offer a form of comfort to parents: “ There are limits to what parents can control. If your baby cries a lot, it doesn’t necessarily mean that you are doing something wrong. »
This observation does not in any way minimize the stress generated by repeated crying. but it replaces things in a more nuanced does your baby cry no biological context. It also means that tirelessly looking for the cause of behavior can sometimes lead to an impasse. because the origin is simply … genetic.
What about sleep?
The study was not limited to crying. The researchers also analyzed two other key parameters of infantile behavior: the time to fall asleep and night awakenings. Unlike tears. these two aspects of sleep seem much more influenced by the environment than by inheritance, at least in the first months of life.
At two months, the sleeping time is essentially conditioned by habits, stimulation or the quality of interaction with parents. At five months. genetics are starting to play a more notable role, suggesting a rapid evolution of sleep as the baby’s nervous system develops.
As for night awakenings, they appear almost entirely determined by environmental factors, according to the authors. In other words. unlike crying, it is does your baby cry no here that parental efforts can really make the difference, in particular by establishing regular bedtime routines and optimizing the sleep environment.

A part of unknown remains
In addition to the genetic heritage and the environment shared by twins (such as the family home), researchers identify a third component: the unique environment. This term designates everything that differentiates two children from the same home. including subtle changes in the way in which each infant is neat, manipulated, or stimulated. Sometimes invisible differences but which can, on a baby scale, count.
It is also does your baby cry no possible that unidentified organic factors (small digestive pain. sensory sensitivity) come into play, without being captured by the parental questionnaires used in the study.
A step towards a better understanding of infant development
This research is part of a larger study. which will follow the twins up to their three years. The objective is to better understand how early behaviors – crying. sleep, emotional regulation – evolve over the course of development, and to what extent they are shaped by DNA or the environment.
These results are not intended to unleash parents. but to provide them with a more realistic framework on what they can – or not – influence. They also recall how unique each child is, even from the first weeks of life.
So. the next time you wonder why your baby is crying tirelessly, remember that the answer may be hiding deep in does your baby cry no itself. And that it is not a parental failure, but simply the nature that is expressed – in its own way.
