In multiple-child families, the second-born is more likely to be diagnosed with the disorder than the older sibling, according to research carried out by scientists at the Massachusetts Institute of Technology. The study, published in The Journal of Autism and Developmental Disorders, is the first to show that the risk of ASD increases with the number of children in a family.
It is based on data from the National Longitudinal Study of Adolescent Health (Add Health), a longitudinal study of the health and development of young people from birth to 18 years of age. Health study is a collaboration between the University of Michigan and the Centers for Disease Control and Prevention (CDC) and is funded by the Bill and Melinda Gates Foundation, the Robert Wood Johnson Foundation and other philanthropic organisations, including the Wellcome Trust.
“This is an important study because it shows that autism is more common in families with multiple children,” lead author and MIT professor of epidemiology and biostatistics David Schulman.

Why is the second child more rebellious?
According to an economist from MIT in the USA, second-born children are more likely to be troublemakers because of how their parents raised them. Doyle and his colleagues found that children who were raised by their mothers were more prone to aggression than those who grew up with their fathers. This was true even when the researchers controlled for a number of other factors, such as the child’s age, the mother’s education level and the father’s income.
The researchers also looked at how the children’s mothers and fathers interacted with each other, as well as with other children and adults. They found a strong link between mother-child interaction and aggression, even after controlling for other variables. In other words, if a child is raised with a mother who is aggressive, he or she will be more aggressive as an adult, regardless of whether or not the parent is a good parent or a bad parent.
It’s not that the parents are bad or good, but that they interact with one another in a way that makes them more or less aggressive depending on how they are raised. This is not to that parents who are good or bad don’t have an impact on their children.
What is the 2nd child syndrome?
Second child syndrome or middle child syndrome is when the second-born or middle-born child is not comfortable with the presence of their siblings. When the parents give more attention to younger children and less to older children, it can be because of the lack of importance.
In some cases, it can also be caused by the fact that the older child is more mature than the younger child. In this case, the child may feel that he or she is not as important as his or her younger sibling. This can lead to a conflict between the two siblings, which in turn can result in a split in the family.
Why is the birth of a second child so hard on marriages?
The stress of baby #2 can be too much for a lot of marriages. Syndrome is a real problem, but it’s not caused by having a child – it’s most often caused by excess stress and lack of balance in a marriage.
It’s a phase that many can survive if they take the time to learn how to deal with it. If you or someone you know is dealing with this issue, I’d love to hear from you. Please leave a comment below.
What’s the best age gap between kids?
The recommendation of 18 to 24 months is still followed by many experts. It’s best to space pregnancies between 18 and 24 months apart, according to Kecia Gaither, MD, double board certified OB-GYN and maternal-fetal medicine and director of perinatal services at NYC Health + Hospitals/Lincoln.
“If you’re going to have a baby, you want to make sure you have the best possible chance of having a healthy baby,” she . “You don’t want your baby to be born with a condition that could be life-threatening.
Which sibling is usually the smartest?
Oldest children are the smartest, research shows If you’re the youngest or middle child in your family, get ready for some unwelcome news: Your eldest sibling is likely right when they brag about being the “smartest kid in the room.”. A new study by researchers at the University of California, San Diego, found that children who are born to older parents are more likely to be smarter than their younger siblings.
The study, published in Psychological Science, looked at data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a longitudinal study that tracked the health and development of more than 2,000 children born in California between 1988 and 1994. The researchers found a strong correlation between the age at which a child was born and their intelligence quotient (IQ), which is a measure of a person’s ability to learn, think, and solve problems.
In other words, the older the child is when he or she is born the smarter they are. For example, if the average IQ of an 8-year-old was 100, then the oldest child would be expected to have a score of 100 on the Add Health IQ test, which measures IQ at age 8.
Which child is more successful?
First-born kids are more likely to achieve traditional success than their older siblings. Middle-born children often embody a mix of older and younger siblings, which can make them more difficult to predict. For example, if a child is born to a first- or second-generation immigrant family, he or she may be less likely than other children to become a CEO.
But if the child was born in the U.S. to an American mother and an immigrant father, his or her chances of becoming an executive are much higher. The same is true for children of immigrants who immigrated to the United States from other countries, such as those from Mexico, India, China, or the Philippines.
Which child is most rebellious?
Second-born children are more likely to exhibit rebellion, according to a study. That goes double for second-born girls. Doyle’s research, published in the Journal of Economic Behavior & Organization, found that children who were born to mothers with a high level of education were twice as likely as children of lower-educated mothers to engage in delinquent behavior, such as truancy, vandalism, theft, and vandalism of property.
In addition, children whose mothers were high-school dropouts were more than three times as prone to delinquency as their peers who grew up in middle- and upper-class families. The study also found a strong correlation between a mother’s education level and her child’s likelihood of being arrested for a violent crime, as well as his or her likelihood to be suspended or expelled from school.
