Parents of young children often ask the question, at what age should my child be doing ‘X’? To answer this question, it’s important to understand the difference between chronological age and neurological age. While a child may be at the recommended chronological ‘age’ to complete a task or activity, their ability to function and complete the task or activity is reliant on their neurological ‘stage’ of development. The key message in this article is that there is no rush to progress through levels. It may be that a child stays at a particular level for an extra term to consolidate skills. At all levels, being the biggest fish in the pond can do wonders for confidence and skill progression. A happy, confident child learns well.

Chronological age is straightforward. It’s your child’s actual age – the number of years, months and days since birth. Neurological age is a little more complex, as it refers to the ‘stage’ or level of maturity of the brain and the body. We can measure a child’s neurological stage by assessing visible skills such as physical capabilities, speech and language skills, emotional responses and social capacity.

Not all children develop at the same rate, so chronological age does not always match the neurological stage at which a child is functioning. The rate of neurological development is closely associated with the kinds of experiences that a child has in the first years of life, while chronological age just keeps increasing, regardless! Neurological development may be hampered by birth trauma, high levels of stress, or illness that affects brain development, or it may be enhanced by exposure to stimulation that drives rapid neural ‘wiring and firing’. For example, a child who experiences lots of love, movement, communication and the chance to explore the world to gain real-life trial-and-error learning experiences will mature neurologically more quickly than a child who misses out on those experiences. It’s also possible that some children take a little longer to move from one stage to another for no obvious reason at all.  So, it’s not unusual to see many variations in developmental ‘stages’ between children who are all the same ‘age’.

What’s the best way to determine neurological age?

At GymbaROO-KindyROO we know that movement skills closely reflect the stages of brain development very easily and accurately. Of course, some children will have more well-developed movement skills than others, but many children who have a mismatched neurological stage and chronological age often also have movement challenges of one sort or another.

If you are concerned that your child’s neurological stage does not match your child’s chronological age, there are a number of assessments available through your local Child Health Nurse or doctor.

What are the neurological stages appropriate for each chronological age?

While every child develops neurologically at their own rate, the developmental guidelines provided by your local health professional give a good ‘rule of thumb’. GymbaROO-KindyROO’s neurological/gross motor movement developmental model also provides a guide.

It is important to remember that it’s not when your child goes through a particular neurological stage, but that they do.  So, if your child is three years of age and is not managing some of the expected neurological skills, such as the motor skills of jumping, hopping and galloping, don’t panic! Just provide them with the opportunity to practise not only these skills but also the earlier ones, as these lay the important neurological pathways that provide the foundations for these harder skills.  Once your child gets these basic neurological stages firmly embedded in the brain wiring, they can start to achieve success with the expected tasks.

While age marches progressively upwards, neurological development is dramatically affected by the experiences your child has. It’s not just a matter of ‘good luck’, or ‘wait and see’, or even, ‘they’ll get there eventually’. Children need to be actively provided with the kinds of experiences that promote neurological growth.

At GymbaROO-KindyROO we provide your children with exactly the right activities for their age and stage of development, making sure that each child develops to their full potential and that neurological age marches alongside chronological age. By building the neurological system step-by-step from foundational skills to complex skills, we ensure that children are ready academically, emotionally, physically and socially for the challenges of the school classroom.
