Cognition milestones – How you can use these to help your child develop

There are consequences for both our actions and inactions in life. As Einstein said, “Everything that exists in your life, does so because of two things: something you did or something you didn’t do.” The consequences of not acting on a child’s delayed cognition/learning milestones can be profound. As parents, we need to be aware of these milestones, so that we can act if they are delayed. It’s important to act because delayed cognition can have a massive impact on a child’s independence, learning, education, inclusion, career, employment, and their capacity for life-long learning. Moreover, a delay in this important area of development can negatively impact a child’s self-esteem, confidence, emotional well-being, psychosocial health, happiness and much else. And all of this is preventable.

But what does cognition mean? To understand this, we need to remember that learning is the process of achieving a set of skills or acquiring certain knowledge. Cognition, therefore, refers to the mental processes involved in learning. Hence, cognition includes cognitive processes such as the ability to read, think, assess information, recall, reason, imagine, problem-solve, and pay attention.  Acquiring and honing these cognitive processes will continue to be vital in our ability to adapt, survive, and thrive in this fast-changing world.

Milestones show whether your child is developing as expected. Cognition milestones have been shown to develop on a well-established trajectory. Therefore, a developmental paediatrician can use this knowledge of cognition milestones to help identify developmental conditions such as Specific Learning Disabilities (SpLD) and Learning/Intellectual Disability (LD/ID). Likewise, the knowledge of cognition milestones can help us identify co-morbid learning difficulties in neurodevelopmental conditions such as autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and Learning Disabilities (LD).

As one can appreciate, there is variation in the achievement of these cognition/learning skills. In this article, I have covered what are the cognition milestones in a typically developing child. At the end, I have written about how you can help your child reach these milestones. Before you read further, please note that while each milestone listed below is important, missing a single milestone in the absence of anything else is unlikely to be significant. A delay in developing several of these milestones across age bands, deserves prompt attention and merits a neurodevelopmental assessment.

How we can help our children reach these important milestones

Children learn best through play and experimentation. Hence, involving them in building with Lego/stackable toys, reading books, playing board games, involving them in memory games, telling stories and jokes, etc, can all help in boosting your child’s cognition. Providing them with opportunities to practice and explore will help. Break down the task into smaller chunks and offer them cues and feedback. Moreover, having adequate sleep, a balanced diet, being physically active and time outdoors can all help improve their neuroplasticity, memory, and learning. Alongside this encouragement, praise and reward work wonders. Discouragement or negative feedback can become barriers to their learning.

In conclusion,

As you can see from the above, knowing these cognitive milestones can offer crucial indications about your child’s learning and cognitive abilities. These cognitive milestones can help you monitor your child’s progress and development. They can help reassure you and continue to enjoy being part of your child’s learning journey. However, if you are worried about your child’s learning, then don’t ignore your gut feeling. Try and discuss your concerns with your child’s teacher or your health visitor.

I regularly see children who are about to transition to secondary school but have not met the cognitive milestones for a 5-6-year-old. It is crucial to seek help for your child as soon as possible, as early intervention can prevent your child’s learning/cognitive delay developing into a learning disorder or a learning disability. Furthermore, seeking help early can prevent development of psychosocial problems of low self-esteem, reduced confidence, avoidance of learning activities, school refusal, low mood, anxiety and behavioural problems.  On the other hand, identifying their difficulties early can lead to effective interventions which in turn can enable their learning and facilitate gaining valuable qualifications and financial independence.  Therefore, it’s important to know what the cognition milestones are, and how you can use your knowledge of these to help your child’s development.
