Our son has always been the mouthy type, and he’s been that way for as far back as I can remember. If you have a mouthy kid, you know how annoying that behavior can be. Mouthy kids have a response for – and an opinion about – EVERYTHING. They challenge EVERYTHING. And they drive you crazy.
Discovering about how personality influences children’s behavior helped us understand our son better. It helped us become aware that certain characteristics are part of children’s nature and instead of focusing on “getting rid of them”, we need to parent with those characteristics in mind.
For instance, instead of trying to “change” our son, we focused on teaching him that although he is free to express his opinion, he should do so with respect and accept that there will be many occasions on which others will have a different viewpoint.
When children are still little, some of their behavior traits seem “problematic” and as parents, we may be tempted to change them. But many of the characteristics that are frowned upon in childhood actually become strengths as your child grows older.
- If a “mouthy” child is taught to mind how they express themselves, they become an adult who is not afraid to disagree respectfully
- An “overly emotional” child who is taught to express their feelings instead of repressing them becomes an adult who is sensitive to others’ feelings
- If a child who pays too much attention to what others think of them is taught that they too matter, they become an adult who knows when to let go
Children – like everyone else – have very different personalities. There’s the kid who’ll smile at you when you’re yelling your loudest, and then there’s the other one who will burst into tears if you as much as whisper too loudly.
If you have several kids, you’ve probably already noticed minor or major differences in their personality. One of your kids might be the “attention seeker” who thrives on being watched, and the other one may be a “silent observer” who is attentive to everything and everyone around them.
Different children have different personalities, and these personalities affect their behavior. This may explain why one discipline strategy that has always worked with your first two kids can be a miserable failure with your third one, or even why, despite raising all your kids with a focus on non-materiality, one of them may appear to be interested only in material things.
The challenges of determining personalities in childhood
Children can change at a dizzying speed and it is not uncommon for a child who was described as a “painfully shy” toddler to become a “boisterous” preschooler.
Determining a child’s personality can be a tricky and misleading affair because childhood is a period of development, meaning that your child is still acquiring cognitive, social and emotional skills which will affect their behavior.
Also, your child’s environment and even your parenting style has a large impact on their behavior. For instance, if a child’s natural tendencies are overlooked or stifled in any way, then they can lean on their other functions. In such a case, such children experience great distress, frustration, stress, anxiety or even feelings of shame.
And then, “for every rule, there is an exception”.
That said, children’s personalities tend to remain relatively constant because their dominant function, meaning the most well-developed one, develops in childhood.
This dominant function is usually fully developed by the time your child turns 13 and describes a large part of their personality. For example, if your child’s dominant function is extroverted, they will usually display extrovert behavior. But other factors also intervene, which explains why, for instance, all extroverts do not behave exactly the same.
There is A LOT to be said about children’s personalities and about the different functions that all have an impact on your child’s personality – I couldn’t possibly cover everything here.
This article proposes a brief overview of what to expect of your child depending on their personality type.
Understanding the different types of child personalities
Every child has their own unique personality. This influences their behavior right from the toddler years. A more adventurous or curious child might start crawling or walking earlier, and a shyer one may take a longer time to explore the unknown.
Although identifying personality types in childhood should always be treated as a simple “guide”, being more aware of your child’s dominant function can help you understand them better and allow you to parent with their temperament in mind.
The Myers-Briggs Personality Type Indicator (MBTI) is one of the best known tools for identifying personality type, even though it has several shortcomings. It was developed by a mother and her daughter who felt that the more people were able to understand themselves (strengths, weaknesses, preferences), the easier it would be to make better life choices and to lead happier lives.
The MBTI proposes 16 personality types based on four different scales:
- Extraversion (E) – Introversion (I): Distinguishes between extrovert and introvert behavior.
- Sensing (S) – Intuition (N): Refers to how your child gains information. It distinguishes between people who gather information primarily by sensing the things around them and those who do so based on intuition.
- Thinking (T) – Feeling (F): Refers to whether your child makes decisions based on their feelings or on logic.
- Judging (J) – Perceiving (P): Refers to how your child organizes their environment
Depending on these preferences, a four-letter code is used to determine your child’s personality type.
Understanding your child’s personality
Understanding your child’s personality will make it easier to understand their behavior. It can also help you determine what activities are best suited for your child and which are best avoided.
Knowing that your child is not simply being “unreasonably stubborn” can also change your parent-child relationship and modify how you view and react to their behavior.
As I mentioned earlier, there is so much to be said about the characteristics of different personalities that I couldn’t possibly cover it all here.

As I mentioned earlier, the article above presents a very brief overview of personality types. I have prepared a free guide with additional characteristics to help you get a clearer idea of your child’s personality type and, more importantly, to give you tips on the best way to take their personality into account in your parenting.
Remember that this is just a guide and not a professional assessment of your child’s personality. Only a trained professional can administer the real MBTI and give you an accurate interpretation of the results.
When determining your child’s personality, please remember that children are still developing and changing, meaning that before age seven, you are unlikely to be able to determine their “real personality type”. Even after age seven, many things are likely to change as they grow older.
Also, the environment in which they are raised, and your parenting style, can influence their behavior. And, lastly, children often act in unexpected ways: a child who needs months before they can get accustomed to their new teacher may fall in love with their swimming instructor on sight.
In other words, nothing is set in stone, meaning that it is important to think of this guide as just that: a “guide” usable in the present moment.
Can you change your child’s personality?
It is not uncommon for a parent with a shy child to wish that they were “more outgoing”, or one with a “talkative one” to wish that they could “listen to others a bit more”. That’s something that many parents do, but it is important to understand that your child’s personality is not “right or “wrong” or “better or worse” than any other child.
Remember that certain traits that appear challenging in childhood will actually be a strength as your child grows. Once you accept that your child is unique and perfectly okay just the way they are, it will be easier to understand and accept their behavior.
Having a better understanding of your child’s temperament will make it easier to manage challenging situations. For example, knowing that you have an INFJ child will help you avoid overexposure to over-stimulating environments.
As promised, here is a free downloadable guide with more information about the different strengths and weaknesses of your child’s personality type and simple parenting tips that respect their temperament.
