While narcissists often fly under the radar, with little known research regarding their day-to-day life and behavior, one’s parents may have to disagree. Not only are narcissists more likely to exhibit selfish behaviors such as manipulation and condescending language, but they are also willing to compromise close relationships to boost their ego or assert their superiority.

While these parental relationships are deeply important, ca neuroscience research suggests, it inherently binds us with an innate sense of trust; having a narcissistic child can burden you with guilt, make you feel unworthy, and leave you feeling unappreciated as a parent. Recognizing the signs your adult child is narcissistic, according to psychology, can help you set better boundaries.

Here are the 10 signs your adult child is a narcissist, according to psychology:

1. He acts impulsively

If you’ve noticed your adult child rushing to make big decisions, from jumping into a new relationship to making a big purchase or booking a plane ticket with hours to spare, they may have narcissistic tendencies. More concerned with the outcome of a big life change or decision—the attention of others—narcissists will reject the important prelude to making them.

A journal published in the National Library of Medicine argues that the narcissist’s overconfident personas and strong egos often push them to make these bad decisions. With a mixture of impulsiveness, rejection of expert advice, and misplaced superiority, they are more likely to misjudge a situation and make a decision that harms themselves or others.

Failure to take responsibility for these decisions can also be a sign that your adult child is a narcissist, according to psychological research, as they are often shifting blame and capitalizing on false self-confidence to protect their image.

2. They are outgoing and sociable

With an inherent need for attention and validation from others, narcissists often harbor a large and ever-evolving social circle of friends, coworkers, and acquaintances.

According to one Journal of Psychological Inquiry published in 2001these energetic, sociable, and outgoing tendencies are typical of a person with a narcissistic personality—they thrive on being liked or admired by others.

As a parent, you may notice this need for external validation early in your child’s life, as they are often more expressive while speaking, have an unsettling assertiveness, and a high energy level.

In adulthood, this can manifest in many ways, but most commonly as a hyper-confidence that tends to inherently attract others, especially those with deep insecurities which aligns with the inner turmoil of a narcissist. That is why narcissistic workers often get higher wages and promotions at work—are willing to do anything to please their bosses and paint themselves as the most competent and confident.

3. They lack true empathy

Despite having better emotional recognition than the average person, appropriate a journal of Front Psychiatrysuch as the ability to understand someone else’s sadness or vulnerability, most narcissists are not truly empathetic. While one may pretend, as research suggests, to support other people’s emotions, this is often based in a self-serving activity such as manipulation.

So, while they may recognize and recognize other people’s emotions, they are unwilling to support them unless it helps support an internal superiority complex or profit.

A fundamental aspect of our connection with othersit can be difficult to come to terms with your adult child’s lack of empathy as a parent. With damaged boundaries, you will continue to feel only the guilt and shame that comes with every interaction, but with the right support you can move on and nurture a healthier relationship.

4. They feel entitled to your time and energy

Especially for parents of narcissistic adult children, many people in their lives feel burdened by their constant needs for attention, help, support, and favors. Narcissists inherently feel entitled to everyone’s time, space, and energy, but especially the people they have formed relationships with in their lives.

Without healthy boundaries to their relationship, these parents will do anything to help their children, but are often taken advantage of and shamed. Narcissistic children may even use their diagnosis as a means of blaming their parents, arguing that it is their fault that they need help or are in the situation they are in.

However, ca a research article from PNAS argues, the origins of narcissism in children are multifaceted and inherently complex. While a parent’s behavior has the power to greatly influence their children’s lives, it is not entirely to blame for the presence of narcissistic traits.

5. They are capricious

With a fragile ego and deep-seated insecuritiesnarcissists who do not receive enough attention or validation from others often struggle with intense mood swings and frustration.

Of course, even when they receive this attention from others, most of their relationships are inherently shallow—driven by their own needs and manipulative tactics—perpetuating a cycle of isolation in their lives that also causes moodiness, depression, and anxiety.

6. They use your triggers and insecurities against you

Since their ability to read people extends to any situation, many narcissists can use people’s vulnerabilities against them in arguments or conflicts. If your adult child knows that you fight back by yelling, he will grow louder and louder until he gets what he wants.

If they’re aware of your insecurities with your body, relationships, or even your job, they’ll be the first to attack those things when you set boundaries, say “no,” or try to call them out on their behavior.

Narcissists often use more swearing, foul language, and insults than the average, appropriate person studies from the Journal of Language and Social Psychologynot just because they are more confident and confident in their ability to do whatever they like, but because they seek attention.

This tendency to swear, whether they don’t care or are simply looking for attention, is one of the telltale signs that your adult child is a narcissist, according to the psychology of self-serving behaviors. It can also be characterized by a narcissist’s inability to trust, even with close relationships such as their friends or parents.

They will swear at a family member during an argument, even when they are lying because they he does not care to justify his intentional deception. They are willing to manipulate others into believing they are being honest.

8. They “love to bombard” you.

While many people just understand “love bombing” or “intermittent reinforcement” in the context of a romantic relationship, it can also appear in platonic and parental relationships.

Narcissistic adult children may shower their parents with gifts, spend a lot of time with them, and pretend to support them with conversations, advice, and even forced empathy, but it’s just their means of conditioning.

They want you to feel committed and, more importantly, indebted to them every step of the way, so they’ll use the “love bomb” to get into your good graces. This cycle of reinforcement is not only manipulative in any kind of relationship; is one of the most obvious signs that your adult child is a narcissist, according to psychology.

9. They rely on you for validation and confidence building

According to the book Psychological perspectives of praisesome adult children inherit narcissistic tendencies from being “praised” by their parents growing up. Although it is rarely the only reason they become narcissistic, this behavior and cycle of reinforcement often continues into adulthood.

Adult narcissistic children will continue to look to their parents for validation and attention, especially when they can’t get it from others – from intense praise for their career to superficial compliments on their looks, they will crave it.

10. It spoils special occasions and holidays

With a selfish, “all about me” attitude, narcissistic adult children hate sharing the spotlight with other people, events, and celebrations. They will often sabotage gatherings that are not entirely about them.

Whether they’re engaging in attention-seeking activities, talking down to attendees, or generally causing mayhem, they’re not shy about setting the tone of events in favor of their need for validation. But don’t call them for it, like ScienceDirect Studies suggests, because most narcissists only become more agitated when they are meant to be embarrassed in groups.
