Children (1 year through 12 years) Adolescents (13 years through 17 years. They may also be referred to as teenagers depending on the context.) Adults (18 years or older)
Kids between 8 and 12 are called “tweens” because they are in between children and teenagers. It's very normal for kids this age to start to move from being very close to parents to wanting to be more independent. But they still need a lot of help from their parents. Kids this age go through big physical changes.
Adolescence (generally defined as puberty through age 18) Young adulthood (generally defined as 18 to 22 or 18 to 25) Later adulthood (generally defined as mid-20s and older)
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.
By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.

As children reach the age of 10, many will start to think of themselves as being almost teenagers. While some 10-year-olds will start looking and acting more mature, others will remain more child-like, both physically and emotionally. "Ten-year-olds are emerging adolescents.

The brain still developing into a person's early or mid-20s. A person becomes a teenager when they become 13 years old. It ends when they become 20 years old. Teenagers who are between 13 and 17 years old are considered both children and teenagers in most countries.
The answer to this question in international and domestic law is clear: a child is anyone under the age of 18.
If our various child parts are not fully integrated into our adult self, we're likely at times to feel like a child inside an adult's body. We won't be able to feel truly grown up because our basic sense of self hasn't sufficiently evolved into the actual adult we've become.
Adulthood is commonly thought of as beginning at age 20 or 21 years. Middle age, commencing at about 40 years, is followed by old age at about 60 years.
First crushes may occur at any time, but generally start at around 10-13 years of age. They are an important step in developing normal and healthy romantic relationships, and provide opportunities to learn how to compromise and communicate.
The "tween years" can be challenging for both children and their parents. Young adolescents are continuing to explore their community and world and beginning to develop unique identities separate from their parents.
The definition of 'tween' varies, with some using it describe children aged 10-14 years, some 8-12 years and others who use it only to describe girls… but I think the most accurate definition of a tween or 'tweenager' is any child, boy or girl, aged 9-13 years.
