The English language includes various terms for small children aged from birth to 4 years. Often the terms are used interchangeably. However, those terms may mean different things to each individual. Some people call small children babies even if their children cross 4 years of age. On the flip side, some parents call them kiddies or toddlers.

You may wonder what if you call a kid a baby. As a parent, you may even call your teenage a baby. So, what would you benefit by categorizing the child into particular terms based on his age? Well, small children need to be monitored, nurtured, and administered suitable nourishment and medicines from time to time.

When you visit a supermarket, you’ll find items labeled as “for toddlers” or “for infants”. Knowing the right terms will let you choose the right nourishment and medicines. Also, keeping informed will let you take appropriate steps for your child’s growth and development.

Newborn age range

The term newborn actually refers to a newly born baby. According to doctors and experts, a newborn age range is a baby aged between 0 and 2 months. The World Health Organization defines a newborn as a baby that’s less than a month. During the first two months, appropriate feeding and care are essential to enhance the child’s likelihood of survival as well as to lay a foundation for his healthy life.

Growth and development

When a baby is just born, he usually cries to signal needs. Ideally, the newborn will cry when he feels uncomfortable or hungry. He may also cry to draw your attention toward his pain or other ailments. As a parent, it’s your duty to respond to those signals and ensure you meet his needs.

As the nervous system gets matured, the child becomes capable of using his thoughts into actions. Soon the newborn will use subtle actions to communicate and interact with you. You may notice bodily gestures during this period. The newborn will seek communication and express his feelings with sounds and facial gestures.

During this stage, newborns listen to and try to absorb the basic, distinct language sounds. This process serves as the basis for speech. Attachments to parents and primary caregivers are normal during this phase. Your child hears well and responds to loud, high-pitched sounds after some days.

His vision develops quickly, but it’s weak. Newborns entertain and control their movements through reflexes by exploring their toes and fingers. They also develop bonds of trust and love with their parents and caregivers as a part of social and emotional development. The way you cuddle, hold, and play with your newborns will form the foundation for how they’ll associate with you and others.

Infant age range

The term baby, infant, and newborn are often used synonymously. However, there’s a difference between these terms. As stated earlier, a newborn is a baby aged between 0 and 2 months. On the other hand, an infant age range is a baby between 0 and 12 months.

During the first six months, exclusive breastfeeding is highly recommended. Crying and fussing are the primary types of communication. Infants react to touch, turn toward a voice, and seek out the bottle or his mother’s breast.

During the infancy phase, babies develop an exclusive bond with their caregivers and parents. They learn to clap, smile, wave, babble, pick up objects, and crawl. Some babies may even start talking using a few rods. At the age of around 6 months, infants are in a position to roll over and sit properly without any kind of support.

In this stage, infants learn various things such as focusing their vision, reaching out, exploring things around them, and a lot besides. By the end of the year, some infants even learn to walk.

When the child reaches 2 years of age, he tries to walk around and moves here and there. Toddlers love songs, rhymes, and simple games.

An average toddler reaches about half his adult height by the time he becomes 3 years old.

Baby age range

The term baby is used to refer to a child from birth to 4 years of age. Newborns, infants as well as toddlers can be called babies. In a nutshell, a young offspring is referred to as a baby.
