If you have had a child or been around children you will likely have noticed most children act the same at different ages. This is called developmental milestones. As children grow it is important they hit milestones at certain ages so they can grow and mature on time. There are four stages of childhood. The first is infancy/toddlerhood, little kid, big kid, adolescents. Child experts, doctors, and parents all look at milestones to know if the child is on target, ahead, or behind in growth.
Infants and Babies
The CDC explains the infant and baby stage is from birth to 2 years old. This stage is when the baby is learning so much and the brain is developing at a rapid speed. Infants, until 2 months old can get calmed when spoken to or are picked up, and seem happy when you walk up to them. They begin to coo and babble, and react to sounds. Babies look at toys for a few seconds, and watch movement. They also move both hands and legs and learn to grab things.
By 6 months old babies know familiar people, laughs and makes squealing noise, put things in their mouth to explore them, rolls from tummy to back, and leans on her hands to support herself while sitting. At one years old babies can play games like patty cake, they wave bye and can say Moma and Dada. One year old's also understand the meaning of no, put things in a container, and pulls up to a stand and walks holding onto things (CDC, 2023).
When babies are 18 months old they should be able to move away from you and look for you when your nearby. They also look at books, put arms into sleeves and legs into pants, and can follow single step directions. Babies that are 18 months old can copy simple chores, and play with toys in simple ways. They should be able to walk on their own, hold a sippy cup, tries to use a spoon, and can get onto a couch (CDC, 2023).
Toddlers/little kid
Toddlers are ages 1-3 years old, and little kid is 4-6 years old. Some common developmental milestones for two year old's are noticing when others are hurt or upset. They can put two words together, point to at least two body parts when asked, do gestors like blowing kisses and nodding yes. Two year old's can kick a ball, run, walks up a few stairs without help, and can eat from a spoon. Three year old's can calm themselves down. talk in conversations with at least two back and forth, can say what action is happening in a book, and say their first name when asked. They can draw a circle when shown how, uses a fork, puts things onto string, and put some clothes on by himself (CDC, 2024).
Four year old's begin pretend play and like to pretend they are someone else when playing. Four year old's can comfort others, answer simple questions, they can name a few colors, and unbutton some buttons. Five year old's follow rules and take turns, they recognize simple rhythms, count to ten, and use numbers about time like tomorrow, and they can hop on one foot. Six year old's can count backwards, have everyday skills down (CDC, 2024). They also start to loose baby teeth, learn to express themselves through words, and learn to write. Six year old's often feel like big kids, read simple words, catch a ball, skip with ease, and draw a person with at least 8 parts (Healthwise Staff, 2023).
Big kid
Big kids are children ages 7-11 and are much more active than younger children. They enjoy a lot of activities and want to stay busy. They can ride a bike, jump rope, and tie shoelaces. They can also do simple math like addition and subtraction. Children age 8 years old jump skip and chase, they can dress and groom for themselves, and use simple tools like screwdriver and hammer. Older kids 9-11 perfect skills, and are able to write, draw, and paint (CHOC, 2023).
Teenagers
Teenage years, some people hate them while others love the years. John Hopkins calls these years the growing years, the stage is from ages 12-17 years old. For boys puberty begins between ages 9 1/2 and 14 years old. For girls puberty is from ages 8-13 years old. During puberty the body grows and changes so rapidly. They begin to have hair on their face and under their arms. During this time adolescents begin to think abstractly, they can also think long term and set goals. Teenagers want acceptance by their peers, their friends revolve around their world, and parents are put on the backburner. Teenager might also take on new challenges (Johns Hopkins Medicine, 2020).
Each stage is unique and fun. Oftentimes adults find a specific age challenge to work with. The best thing a parent can do for their children is spend time with them. Let them know you are there, ready to listen, and be a guide.
