Understanding Child Behaviour

Child behaviour is influenced by a myriad of factors, including genetics, environment, parenting styles, and social interactions. Birth order adds another layer to this intricate puzzle, offering insights into why children with different birth positions exhibit unique behavioural patterns.

The Influence of Birth Order on Child Behaviour

Birth order theory, popularized by psychologist Alfred Adler, suggests that the order in which a child is born into a family significantly affects their personality and behaviour. Each birth position comes with its own set of expectations, responsibilities, and family dynamics, all of which contribute to shaping a child’s behaviour.

Behaviour of Oldest Children


Oldest children often receive undivided attention from their parents during infancy. This focused attention can foster a sense of security and confidence. They are usually the recipients of parents’ trial-and-error approaches to parenting, which can lead to a strong bond but also to high expectations.


As toddlers, oldest children may exhibit leadership qualities early on. They often take on a more responsible role, especially if younger siblings arrive. This period can see them developing a sense of duty and an inclination to help with caregiving tasks.

Preschool Years

During the preschool years, oldest children may display a high degree of diligence and motivation. They are likely to be more organized and may take on a role similar to that of a ‘mini-adult,’ often helping to enforce rules and routines set by parents.

School Age

In school, oldest children tend to be high achievers. They often strive to meet parental expectations, excelling academically and in extracurricular activities. Their sense of responsibility and leadership skills become more pronounced, and they may take on mentoring roles with peers.


Adolescence can be a challenging time for oldest children. The pressure to succeed and be a role model can lead to stress. However, their early-developed leadership skills and responsibility often help them navigate these pressures effectively, maintaining high standards in academics and social settings.

Behaviour of Middle Children


Middle children, from infancy, often experience a different dynamic compared to their older and younger siblings. They may not receive the same level of intense focus as the oldest child, but this can lead to greater independence and adaptability.


During toddlerhood, middle children learn to negotiate and navigate their place within the family. They might become peacemakers, striving to balance relationships between older and younger siblings, and developing strong interpersonal skills.

Preschool Years

In the preschool years, middle children often exhibit flexibility and strong social skills. They are accustomed to sharing attention and may be more cooperative in group settings. This adaptability can make them adept at making friends and fitting into various social circles.

School Age

At school, middle children might not seek the spotlight as much as their older siblings, but they often excel in collaborative environments. They may pursue interests that are different from their siblings, carving out their own unique identity within the family and among peers.


Adolescence for middle children can be a time of self-discovery. They often continue to build on their social skills, forming strong friendships and exploring diverse interests. Their ability to mediate and adapt can serve them well in navigating the complexities of teenage life.

Behaviour of Youngest Children


Youngest children typically receive a great deal of attention and affection from their parents and older siblings during infancy. This can result in a sense of security and confidence, but may also lead to them being more dependent on others.


In toddlerhood, youngest children often enjoy the freedom to explore and play, as parents may be more relaxed with their youngest child. They tend to be more outgoing and adventurous, testing boundaries and asserting their independence.

Preschool Years

During the preschool years, youngest children are often seen as charming and sociable. They are used to being the center of attention and may use their charm to get what they want. They can also be more creative and imaginative, engaging in playful and imaginative activities.

School Age

At school, youngest children may be less pressured to perform academically compared to their older siblings. They often excel in creative pursuits and social interactions, enjoying a more relaxed approach to learning and school activities.


Adolescence can be a period of exploration and experimentation for youngest children. They might be more willing to take risks and try new things, benefiting from the experiences of their older siblings. Their social skills and creativity often continue to flourish during this stage.

Factors Affecting Child Behaviour Beyond Birth Order

Parental Influence

Parental involvement and parenting style play a crucial role in shaping child behaviour. Consistent discipline, emotional support, and positive reinforcement are vital for healthy development, regardless of birth order.

Socioeconomic Status

Socioeconomic status can impact the resources available for a child’s development. Access to education, extracurricular activities, and healthcare can significantly influence behavioural outcomes.

Educational Environment

The educational environment, including the quality of schooling and the relationships with teachers and peers, can affect a child’s behaviour. Positive and supportive educational settings can enhance learning and social skills.

Personality Traits

Individual personality traits, such as temperament and resilience, also play a significant role in child behaviour. These traits can influence how children respond to their environment and interact with others.


Child behaviour is a multifaceted subject influenced by various factors, including birth order. Understanding the unique traits of oldest, middle, and youngest children can help parents, educators, and caregivers provide better support tailored to each child’s needs. While birth order offers valuable insights, it’s essential to consider the broader context of each child’s life to fully understand their behaviour.
