Why Is Your 9-Year-Old Behaving Like A Teenager? Understanding The Tween Years

"You promised me I could watch that show. So what if I haven't finished my homework? I'm not going to do it now!"

Nine-year-old Rahul is shouting at his mother, Ankita. When she tries to reason with him, he suddenly bursts into tears.

"You promised, but you didn't keep your word. I hate you!"

Refusing to listen to her, he walks off into his room and slams the door.

Ankita is upset and bewildered. She is unable to understand her son's behavior. These days, he is extremely unpredictable. One minute, he is his usual sweet-natured self; the next, he is sulking, crying over small issues, slamming doors, and being disrespectful.

"He has become very emotional and is quick to anger, as well. But he is not even a teenager yet! I cannot understand why he is like this," the worried mother confides to her friends. To her surprise, friends who have children around the same age tell her they are facing the same thing at home. They too are puzzled and do not know how to handle this stage in their children.

Have you experienced this as well? If so, you are not alone. Many parents are surprised when their cheerful child suddenly becomes emotional, argumentative, or unpredictable around the tween years.

Understanding your tween's emotional changes

That children are constantly growing and changing is something you already know. But their behavior changes in small ways as they shed their early and middle years. And as your child nears their teenage years, they go through a complex phase of growth, both internal and external. Some changes are easy to notice, while others, such as emotional, hormonal, and neurological changes, happen quietly beneath the surface.

Why the tween years feel so intense

Psychologist Aarti Rajaratnam points out: "Tweens go through major changes physically, hormonally, emotionally, neurologically, and also have to deal with a sudden jump in academic goals and pressures." 

So much change happening all at once can be difficult to handle, even for adults. Imagine how it must be for your child. 

How you can help

• Recognize and accept the changes your child is undergoing. Isn't it rather unfair to expect your tween to remain the way she was at age 7?
• Note that your child is asserting their independence and opinions. Does it upset you that your child is no longer so dependent on you, or that they no longer require your approval for everything they do?
• Ms Aarti stresses, "A supportive environment is essential. The best way to deal with this age group is for parents (and other adults, like teachers) to be more understanding and empathetic, instead of demanding and punitive."
• Stay connected to your child. Make sure they know that you love them and are always there for them. No matter how they are behaving at the time, your presence—emotional, physical, and psychological—is necessary for your child, especially now.

Why mood swings are common during the tween years

Tweens experience significant mood swings in the course of a day. So, there can be sudden outbursts of anger, sulking, and reacting to seemingly trivial issues. This means your child is also suddenly more sensitive to everything you say. And they may react or respond in a way that disturbs you. It can be challenging to stay calm through these inexplicable behaviours. "Anger is the one emotion that most parents and teachers find hard to deal with because it also manifests as violence. However, even states like extreme anxiety, fear, and sadness are common in the tween years." - Ms Aarti. 

How parents can respond calmly 

• Know that it's normal for tweens to display a range of moods, so do your best to stay patient.
• Your child's anger is normal, and so is yours. Parents are the adults, so they must model emotional regulation for their tweens.
• Remember, how you react or respond to your tween does make a difference.

"With two-way communication and the opportunity to express themselves, most tweens settle down and develop emotional regulation gradually. What's more, the fastest predictor of this learning will be the opportunity to model adults who also deal with emotions like anger effectively." - Ms Aarti

Emotional maturity takes time

Psychologist Dr Sulata Shenoy offers a few tips:

Help your child understand feelings 

• Be empathetic and don't belittle your child's emotions.  Do not say, "Why are you crying over something so silly?"   "Instead, try to nurture emotional maturity in your child, as that is a vital life skill. This requires modeling the emotional maturity for your child, too."
• Recognize that emotions are not right or wrong. What matters is how emotions are expressed. For instance, an extremely happy person may hug another person till it hurts. That response is inappropriate because angry, aggressive persons do the same.
• Look at your own responses to your child's behavior and manage your own emotions better. Sit with your child and get them to open up. Let them know that what they are feeling is okay. In time, they will learn to better deal with their emotions.

When tweens push boundaries and test limits

Your tween may behave disrespectfully or have angry outbursts. They may slam doors and yell at you, saying things like "I hate you!", "You are always so unfair!" and so on. They may not be willing to listen to what you have to say and may ignore you, rebel, or flatly refuse to do something. For instance, if you tell them that television time is over and they must finish their studies now, they may even disregard you. Or, go on to throw a tantrum!

How you can help

Stay firm without taking it personally

• Try not to take it personally when your tween is rude. They do not mean what they say. Rather than reacting or threatening them, give them some quiet time to calm down.
• Then, ask them why they are upset. Listen and try not to interrupt or tell them what to do. Instead of lecturing, allow them to explain. Once everyone has calmed down, reassure your child that your love for them does not change, even when you disagree with their behaviour.
• Be firm and reasonable. Offer help with time management and make sure they know some rules are non-negotiable. Help them prioritize and let them have screen time after their homework and studies are completed.

Everyday habits affect your tweens' emotions

As your child grows and changes, their habits impact their well-being. For instance, your child's moodiness may sometimes be caused by sleep deprivation, leaving them overtired and cranky.

Similarly, unregulated screentime compromises their physical activity and play. Another vital aspect is diet. Sugary cereal for breakfast, and fried foods too often, can play havoc with their health. Stress that builds up between family members can also affect the child's emotional state.

How you can help 

Pay attention to sleep, food, stress, and screens

• Dr Shenoy says parents often overlook the role of external factors. "Hunger, lack of sleep, and stress (at school or home) can aggravate the condition, so it is important to take care of these factors first," she stresses.
• Remember, parents' fights can leave a lasting impression on their child. After all, children are very sensitive and react to emotional undercurrents at home.
• Ensure you give your child nutritious food and cut down on high-salt, high-sugar foods.
• Limit gadget time and encourage physical play. Are there friends your child can play with in the neighborhood? If not, enrolling them in dance, sport, or martial arts can make a difference, building their self-esteem and keeping them healthy and happy.

When should parents seek professional help?

Seek professional guidance if your tween's mood swings are severe, persist for long periods, interfere with school or friendships, involve self-harm, extreme anxiety, prolonged sadness, aggression, or major changes in sleep and appetite. While emotional ups and downs are common during the tween years, significant distress should not be ignored.

Parent Checklist: Supporting your tween through mood swings 

• Accept that mood swings and strong emotions are a normal part of the tween years.

• Listen without immediately judging, correcting, or dismissing your child's feelings.

• Stay calm and avoid taking angry words or outbursts personally.

• Set clear and respectful boundaries while remaining warm and supportive.

• Prioritize healthy routines such as adequate sleep, nutritious food, physical activity, and balanced screen time.

• Spend regular one-on-one time with your tween to stay connected.

• Seek professional support if emotional or behavioral changes become severe, persistent, or begin affecting school, friendships, or family life.

Remember, your tween may be growing more independent, but they still need your love, patience, and reassurance.

Stay connected through the tween years

Your tween may be asserting their independence, but deep down, they need reassurance that you are there. Make the effort to stay connected despite their moods and outbursts. The bond you build will support them through the bigger changes they will experience in the teenage years.
