Dr Clifton suggests a limit of "two or less" kids per family might be good, but says this can't be considered without the impact of our lifestyle on the environment. "A family could have six kids and have less impact than a family with no kids," he says.
According to a Gallup poll, 4 in 10 Americans say three or more children is the ideal family size.
Research suggests that having two children is still most people's idea of the 'ideal' family size. Having said that, according to the Office for National Statistics, one-child families have been on the increase over the last two decades.
Having two children reduces mortality risk. Three different studies looked at thousands of older adults and found the same thing: two kids was the sweet spot for health. The risk of an early death increases by 18% for parents of an only child. Also, the risk is higher for parents of three or more kids.
According to doctors, just after 5 vaginal deliveries or even 3 c-sections, the woman's body does become weak. The risk of uterine rupture and bladder injuries is high and so is the chance of abnormal placentation and ectopic pregnancy.
Experts say the best time to get pregnant is between your late 20s and early 30s. This age range is associated with the best outcomes for both you and your baby. One study pinpointed the ideal age to give birth to a first child as 30.5.
The researchers found that women who had live births had telomeres that were an average of 4.2 percent shorter than their counterparts with no children. This equates to around 11 years of accelerated cellular aging, said Anna Pollack, an epidemiologist at George Mason University and the lead researcher of the study.
According to the London School of Economics and Political Science (LSE) and Western University in Canada, having a third baby won't make you any happier. While parents' happiness increases in the year before and after the first and second children, the birth of third children doesn't see the same increased happiness.
Child number two or three doesn't make a parent happier. And, for mothers, he found, more children appear to make them less happy—although they are happier than childless women. For dads, additional children had no effect on their well-being in his study.
Grow your family to at least four children! According to a study out of Australia's Edith Cowan University, parents with the most life satisfaction (which means those who are the happiest) are those that have four or more children.
The result that they came up with? Having 4 children is the best way to boost your happiness. "Larger families are more chaotic and expensive, this is balanced out by the joy in their lives." the study said.
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.
Since having five or more kids is generally the cutoff point for being considered a “large” family, here are all the ways your parenting will change once you hit that pivotal plus-five milestone.
Three or more children = wrong
Despite the growing trends mentioned above, two children still seems to the ideal number. An actual study revealed one to two children is the ideal number for “happiness”, but with two you don't have to deal with the aforementioned only child issues.
They become quite independent as they reach 5-6 years of age, even wanting to help you with some of the chores! This is probably why most parents look at age 6 as the magical age when parenting gets easier.
Experts recommend waiting at least 18 months between pregnancies because it reduces the risk of your youngest child being preterm or low birthweight (especially if you're over 35). You've got this.
As it turns out, having three kids makes moms the most stressed of any combination of kids, according to a TODAY Parents survey. Mothers of three (naturally) reported more stress than parents of one or two kids ... but moms with four or more little ones actually reported lower stress levels.
Pros of having a third baby
You'll still be able to go out easily as a family of five. Your kids will have more than one sibling. Having three kids may be an easier transition than you think.
A TODAYMoms.com survey of more that 7,000 mothers found that the least stressful number of kids is four, while the most stressful number is three. Scary Mommy blogger Jill Smokler told Today that she wholeheartedly agrees.
In fact, mothers who have three children are the most stressed out - even more so than those who have four, according to a. The study found that while transitioning from two to three children is overwhelming for parents because it means they are outnumbered, mothers tend to 'let go' once they reach four children.
Some 19% have three children, and 8% have four or more. While the association of education and family size remains a strong one, in fact the educational “gap” in fertility has narrowed in the past two decades, driven in part by increases in family size among the highly educated.
As a result, parents find that their mental and physical health takes a big hit with two kids thanks to the effect of chronic stress. And that's especially true for women in cisgendered, straight relationships, where both partners tend to slot, unconsciously or otherwise, into traditional carer/earner roles.
But many first-time parents find that after the first month of parenthood, it can actually get more difficult. This surprising truth is one reason many experts refer to a baby's first three months of life as the “fourth trimester.” If months two, three, and beyond are tougher than you expected, you're not alone.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.
A woman in her early to mid-20s has a 25–30% chance of getting pregnant every month. Fertility generally starts to reduce when a woman is in her early 30s, and more so after the age of 35. By age 40, the chance of getting pregnant in any monthly cycle is around 5%.
