A brief look at child development and the factors that can impact it.

Early childhood is the time from conception to approximately 5 years old. Early childhood, sometimes known as the early years, is believed to be the most essential developmental stage of life. During the early years, critical advances are made in the physical, socio-emotional, and cognitive aspects of development. [1]

What is Development?

Development describes the processes that a child’s body and brain go through. These processes are believed to become more complex as a child transitions into adulthood (puberty). [1][2]

Babies

A baby’s brain develops dependent on the external stimulation of neurological connections gained through experiences. Life experiences, including pre-birth experiences, can have long-term impacts on health and the child’s ability to learn. The brain of a baby is not a fixed structure and does not simply develop based on genetics. Children are usually born ready to engage and explore the world. Babies are active investigators and observers. It is believed that babies actively stretch their own capabilities as they interact with the world around them. Research suggests that during early childhood, babies and young children are naturally driven towards greater learning as they meet challenges, practice, and gain independence. [2]

The First Three Years

During the early years, children’s learning can be rapid as they try to make sense of the world around them. Research suggests 80% of their brain growth and development takes place in their first three years. [2][4][5]

The Importance of Early Experiences

Some social factors and experiences can affect a child’s health and their ability to learn. In social-emotional development, the repetition and depth of experiences are key to a child’s ability to interpret what they hear, how they respond and their observations.

Areas of Development

Early childhood development can refer to many different aspects of development: physical, cognitive, emotional and social, etc. Some early developmental areas involve:

• Memory

• Attention

• Cognition

• Communication and language

• Relationships

• Sensory-motor skills

• Mental health

• Behavioural

• Social-emotional.

These areas cannot be understood separately as they overlap; one influences the other. Therefore, it is important to consider the child holistically to provide the best start in life. The different aspects of child development and health work together to support a child’s overall well-being. [6][8]

Milestones

Milestones should be approached as a guide. Each child is unique and develops at their own pace. Milestones are useful to have a rough idea of child development, although development tends to be a predictable pattern generally. Remember, each child also has a unique past and story, which includes their experiences and the opportunities they have had. It is common that children will reach an area quicker than another child. Numerous factors, such as a low birth weight, a big change or family stress, can affect child development. [2][3][4][6]

Influences on Early Development

As mentioned above, a child’s development and learning are complex and intertwined, and this begins at conception. Socioeconomic circumstances can also determine health and have an impact on early childhood development. There is the concept of ‘nature vs. nurture,’ which refers to the biological and environmental factors that determine how a child develops. Every child has a biological base, but develops in a social setting.

Providing children with security, safety, and a happy childhood is very important. The child’s environment can determine how they learn, their mental well-being, and their health. Relationships are key to children's development and well-being. Early development is significantly influenced by the nurture they receive in their environment from parents, caregivers, family and community. A sense of belonging and a place in community provide a foundation for a child’s developing identity and can enhance learning. [1][2][6][8]

Summary

From conception to preschool, a child’s experiences and interactions have a huge impact on their development. Early childhood experiences and development affect the child’s future. [1][2][6][7][9]
