Newborn boys have higher rates of infection, sepsis, and have poorer survival compared to their female counterparts. The cause of the difference in newborns can be found in the chromosomes, with females carrying two copies of the X chromosome (XX), and males who carry one X and one Y chromosome (XY).
Infant mortality is higher in boys than girls in most parts of the world. This has been explained by sex differences in genetic and biological makeup, with boys being biologically weaker and more susceptible to diseases and premature death.
In times of adversity, newborn girls are more likely to survive. The fact that women have an edge in infancy, when behavioral differences between the sexes are minimal, supports the idea that explanation is at least partly biological, the researchers say.
By most measures of sensory and cognitive development, girls are slightly more advanced: vision, hearing, memory, smell, and touch are all more acute in female than male infants.
It all comes down to biology: Girls just happen to be born with more chemical resilience to stressors. Since boys have less resilience, they're more at risk for neuropsychiatric disorders like autism, early onset schizophrenia and attention deficit disorder.
Are Moms Of Girls Happier Than Moms Of Boys? Moms who have girls are much happier than those with boys, particularly when the children reach early adulthood, according to a study from the Journal of Family Issues. However, a survey done by Gallup says: 54% of Americans say boys are easier to raise than girls.
Mothers are more critical of their daughters than their sons, and admit to having a having stronger bond with their little boys, according to research.
Research over hundreds of years has consistently found that boys naturally outnumber girls at birth.
Anecdotally, many parents say boys reach gross-motor milestones like sitting up, cruising and walking earlier than girls, but some pediatricians swear the opposite. Yet both are wrong: Studies show no significant differences between boys and girls when it comes to these motor skills in infancy.
Is it a household of girls, a household of boys, or a mix of the two best for parents? According to a survey conducted by British parenting website Bounty, two girls are considered the best combination for parents to have a happy and harmonious family life.
In times of trouble, multiple studies have shown, more girls are born than boys. No one knows why, but men need not worry about being overrun by women.
Only 7.6 percent percent of male babies and 5.5 percent of female babies were in the womb 42 weeks or longer. Males were also 1.5 times more likely to be born at 43 weeks or longer. The researchers noted that the most common reason for prolonged pregnancies is an error in calculating the due date.
The greater ratio of boys being born (around 51-52% of live births) has been known since the 17th century. And since the 19th century scientists have known that the mortality of male foetuses in the second half of pregnancy is higher than that of females.
In the womb boys grow faster than girls and are therefore at greater risk of becoming undernourished. Fetal undernutrition leads to small size at birth and cardiovascular disorders, including hypertension, in later life.
1-3 Months
The first three months with your baby often seem the hardest. Sleep-deprived parents can feel overwhelmed, but that is normal and you will quickly learn how to read your baby's cues and personality. Don't worry about “spoiling” your baby at this stage.
Most people find the first six to eight weeks to be the hardest with a new baby. And, although people may not openly discuss many of the challenges in these early weeks of parenthood (if at all), there are a number of common hurdles you may face at this time.
Gifted children tend to begin talking early. While most children say their first word at around 1 year of age, gifted children may begin speaking when they are 9 months old. 2 Some parents report that their children said their first word even earlier than that, as early as 6 months of age.
There is a clear pattern of births across latitude. Here in the U.S., states in the North have a birth peak in early summer (June-July), while states in the South experience a birth peak a few months later (October-November).
Can the Gender of Baby Change During Pregnancy? Sex determination of a baby happens during fertilization, and it can't change during your pregnancy.
Pregnant women carrying girls have a greater chance of experiencing nausea and fatigue, according to the results of a study from the USA's Ohio State University Wexner Medical Center.
Gallup has been polling Americans about their baby gender preferences since 1941, and the results are consistent — there's always a slight preference for sons over daughters.
Dads Prefer Sons And Moms Prefer Daughters, According To Science.
The study found that the prime reason mums wanted daughters was because women felt they would “bond and understand” them better. 32% said they wanted to “dress up their daughter” and “decorate the nursery for a girl.”
According to a survey conducted by British parenting website Bounty, two girls are considered the best combination for parents to have a happy and harmonious family life. In their study, they surveyed 2,116 parents who had children aged 16 and under.
