Childhood is a time of rapid growth and development. Which can sometimes be confusing for parents and caregivers due to differences in individual children. It's essential to understand the typical milestones children reach at different ages, but also recognize that some milestones are reached at different ages depending on the child. This comprehensive guide provides valuable insights into a child's physical, cognitive, emotional, and social development.
Remember as we explore key developmental milestones organized by age, that this guide is meant to help you gain a deeper understanding of your child's expected growth. If your child has not reached these milestones by the expected age, please ask their pediatrician for guidance on next steps.
Infancy (0-12 Months): Foundations of Development
The first year of a child’s life is FULL of developmental milestones. This is the time when children learn the foundational skills they will need to build their motor, communication, cognitive, and social-emotional development throughout their entire childhood.
0-3 Months
At birth, babies can typically grasp objects reflexively and turn their heads toward sources of sound. As they progress into the first three months, they often begin to establish eye contact with caregivers, track objects or faces with their gaze, and respond to familiar voices by turning their heads in the direction of the sound. Motor development also starts to show signs of improvement, with infants making smoother and more controlled movements. Additionally, during this early period, infants begin to demonstrate social responsiveness, recognizing their primary caregivers and seeking comfort and nourishment from them.
4-6 Months
Between the ages of 4 to 6 months, infants continue to make significant developmental strides. Physically, they often gain better control of their head and neck, enabling them to hold their heads up when in a supported sitting position and even during tummy time. Many infants in this age range also start to roll over from their stomach to their back and vice versa. Their fine motor skills are developing as well, with increased hand-eye coordination, allowing them to reach for and grasp objects, bringing them to their mouths to explore.
Cognitively, babies at this stage become more aware of their surroundings and may begin to show interest in objects and people beyond their immediate caregivers, following these moving people and objects with their eyes.
Socially, 4 to 6-month-old infants often become more responsive to social cues and may start to babble and make cooing sounds, which are early signs of communication. They also become more expressive with their noises, attempting to gain attention by babbling.
7-9 Months
In terms of motor skills, many infants in this age group become proficient at sitting without support and may even start to scoot or crawl. They're often eager to explore their environment, reaching for objects. Their fine motor skills continue to develop, allowing them to pick up small objects between their thumb and forefinger.
Cognitively, babies at this stage become more curious and interested in cause-and-effect relationships. They enjoy playing with toys that have moving parts, and they start to understand object permanence. They look for objects that drop from the highchair or parents that have left their vision.
Socially, they may display separation anxiety when their caregivers leave and joyfully welcome them back. Communication skills expand, with increased babbling, attempts at mimicking sounds, and the ability to express a wider range of emotions through facial expressions and body language.
10-12 Months
In terms of gross motor skills, many infants are beginning to transition from crawling to cruising along furniture or walking with support. They gain better balance and coordination, which allows them to explore their environment more independently. Fine motor skills continue to advance, and they can engage in hand gestures like clapping and waving.
Cognitively, babies at this stage become more curious about their surroundings and enjoy activities like stacking blocks, fitting objects into containers, or turning the pages of a book. They can also understand simple one-step instructions and gestures, such as "wave bye-bye" or "give me the toy."
Socially, 10 to 12-month-old infants often become more expressive in their emotions and interactions. They may start to show preferences for certain toys or activities, and their language skills continue to develop, with some babies saying their first words or using gestures to communicate their needs and desires. They become increasingly aware of social cues and may engage in games like peek-a-boo or imitate the actions and expressions of those around them.
Toddlerhood (1-3 Years): Exploring Independence
In this stage, children are working towards becoming more independent.
12-18 Months
By the time a child reaches their first year of life, many toddlers can walk independently and might even start running, climbing, or navigating stairs with assistance. Their fine motor skills have progressed to the point where they can feed themselves with utensils, stack blocks, and turn the pages of a book. Cognitive development at this stage is marked by a growing vocabulary, with some children saying a wide range of words and beginning to form simple sentences. They also exhibit a heightened curiosity, exploring their environment with enthusiasm and understanding basic cause-and-effect relationships. Socially, 18-month-olds often display great joint attention and engagement skills. These skills help children focus on and engage with the same object at the same time. They enjoy interactive play with peers or caregivers, and their ability to recognize and respond to emotions continues to improve.
By 2 years Old
Two-year-olds can typically walk, run, climb, and even kick a ball. Their fine motor skills have improved to the point where they can use crayons to draw simple shapes and manipulate objects with increased dexterity. In terms of language development, 2-year-olds are often chatterboxes, with a vocabulary that continues to expand rapidly. They can typically string together two or three-word sentences and engage in basic conversations. Their cognitive development allows them to understand concepts like "big" and "small," follow simple directions, and engage in imaginative play. Socially, they are becoming more aware of others' emotions, sharing toys, and showing empathy towards their peers. They enjoy parallel play alongside other children and are eager to assert their independence while still seeking comfort from their caregivers.
By 3 Years Old
At 3, children can confidently run, jump, skip, and climb, demonstrating a greater degree of coordination and balance. Fine motor skills have improved, allowing them to string beads, use a fork, and navigate their environment by opening doors. 3-year-olds have a considerably expanded vocabulary and can engage in more complex conversations, express their thoughts and feelings, and ask numerous questions. Their cognitive development enables them to understand concepts like numbers, colors, and shapes, as well as engage in imaginative play, such as creating stories and scenarios. Socially, they are becoming more adept at forming friendships, sharing, taking turns, and showing empathy toward others. They enjoy interactive play with peers and adults and are increasingly independent while still seeking attention from their caregivers.
Preschool (3-5 Years): Preparing for School
During this age, children begin preparing for more formal academic experiences.
By 4 Years Old
By now, children have achieved a remarkable array of developmental milestones that illustrate their growing capabilities. They have honed their coordination and balance, allowing them to run, jump, skip, and participate in more complex physical activities. Their fine motor skills have progressed, enabling them to draw recognizable shapes, use scissors with guidance, and manipulate small objects with precision. 4-year-olds have an extensive vocabulary and can engage in meaningful conversations, express their thoughts and feelings articulately, and tell stories with a clear beginning, middle, and end. Their cognitive development enables them to understand more complex concepts, such as time and spatial relationships. They also demonstrate greater creativity and imagination in their play, constructing intricate scenarios and solving problems. Socially, they continue to develop friendships, cooperate in group activities, and exhibit empathy toward others, making them more socially aware and adaptable.
By 5 Years Old
Children have achieved a multitude of developmental milestones by 5 years old that reflect their readiness for formal education in kindergarten. They have mastered running, jumping, hopping, and are increasingly proficient in activities like riding a bicycle. Fine motor skills have progressed to the point where they can write their names, draw recognizable pictures, and use utensils with precision. Regarding language development, 5-year-olds have a rich vocabulary and can engage in complex conversations, express their thoughts and feelings eloquently, and follow more detailed instructions. Their cognitive development allows them to understand abstract concepts like letters and numbers, as well as focus on activities for at least 5-10 minutes. Socially, they thrive in group settings, forming friendships, cooperating with peers, and showing empathy towards others. They are becoming more independent, curious, and eager to explore the world around them, setting a strong foundation for their educational journey ahead. This stage marks a significant milestone as they prepare for the next step – Kindergarten!
Understanding and tracking these developmental milestones by age is essential for providing the right support and guidance to children. It's important to remember that every child develops at their own pace, and while these milestones serve as a general guide, there's a wide range of normal variation. Celebrate each child's unique journey and provide them with a nurturing environment to thrive in. By doing so, you'll help them reach their full potential and build a strong foundation for a successful future.
If you think your child is not meeting their developmental milestones on time, ask their pediatrician or seek an independent evaluation from an Early Interventionist, Occupational Therapist, Speech-Language Pathologist, or Mental Health Professional to find out next steps.
