The United Nations Convention on the Rights of the Child (UNCRC) defines a child as everyone under 18 unless, "under the law applicable to the child, majority is attained earlier".
In most states in the United States, a child becomes an adult legally when they turn 18 years old1. However, “adults” can mean different things when you ask different people. Let's find out what it means to become an adult according to parents, the law, and science.
This statistically oriented definition of youth, in turn, entails that children are considered those persons under the age of 14. Worthy of note, however, is that Article 1 of the United Nations Convention on the Rights of the Child defines 'children' as persons up to the age of 18.
By 20 years old, a young person is usually considered an adult: their body size is fully grown, they can vote, get married, and many have already entered the workplace. But the evidence suggests that, by many important measures, adolescence continues until around the age of 24 to 25.
18 and older are not typically considered 'children', when comparing children to adults. They are adults. Adults who can still be the children of their parents. Under the age of majority (typically 17 and younger), they are teenagers, but also minors.
Adolescence is the phase of life between childhood and adulthood, from ages 10 to 19.
While most people are in their reproductive prime in their 20s, that decade isn't always the best age to have kids when you consider those important variables beyond fertility. Some people simply aren't ready yet, while others are. That's why most experts and parents agree that there is no perfect age to get pregnant.
But if you're a young mom, you shouldn't feel ashamed. There are a lot of other women who are becoming mothers in their twenties and many women find a lot of benefits to starting their family earlier, such as more flexibility in their careers and more reproductive options.

Section 13 of the Care and Protection of Children Act 2007 (NT) defines a child as a person less than 18 years of age, or a person apparently less than 18 years of age if the person's age cannot be proved.
Most countries have set the age of 18 being the age of majority.
The typical age of attaining legal adulthood is 18, although definition may vary by legal rights, country, and psychological development. Human adulthood encompasses psychological adult development.
The human body is not even fully developed at 18 either. “Under most laws, young people are recognized as adults at age 18. But emerging science about brain development suggests that most people don't reach full maturity until the age 25,” said NPR.
"They have reached adult legal capacity and are fully able to consent to their own care and make adult decisions," says Dr. Woods. However, note that some 18-year-olds will experience a lot of worry around realizing that they are legally considered an adult but aren't sure what their life goals and plans are.
And then there's your health. 20-somethings have a lower chance of miscarrying and of conditions like gestational diabetes, preeclampsia, and high blood pressure. But when it comes to your health later in life, waiting until your 30s to give birth is better.
The optimum age to have a child is when a person is ready- physically, emotionally, mentally and financially. Biologically, 20s might be the best age, but one definitely needs to consider other factors as well before welcoming a baby.
If you are trying to get pregnant after age 50, you will probably need some fertility help. While it's not impossible to become pregnant naturally at 50, it is very rare. Women are born with all of the eggs they will ever have. As you get older, you have fewer eggs, and they are more likely to have abnormalities.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
There is no definitive time or age to have a baby. Everyone is different. Some people feel psychologically well-prepared to have a baby in their early 20s, while others do not.
Who is a child? The answer to this question in international and domestic law is clear: a child is anyone under the age of 18.
As for why the age was changed at all, the reasons behind this include massive improvements in public education since the 21 number was originally set, recognition that 18 year olds were able to enter into legally binding contracts, get married, have children, and could even be forcibly drafted.
adulthood, the period in the human lifespan in which full physical and intellectual maturity have been attained. Adulthood is commonly thought of as beginning at age 20 or 21 years.
