It started out with a simple question. An anonymous mother of an 11-year-old boy asked for help on an online forum.
“How do I tell my wonderful 11-year-old son, (in a way that wonโt tear him down), that the way he has started talking to me (disrespectfully) makes me not want to be around him (Iโve already told him the bad attitude is unacceptable)?”
In other words? Her tween son is going through the start of puberty and beginning to act like a real a-hole and she’s done with it. And, girl. #same.
My son is also 11 and also I’m totally feeling this. He’s been navigating the emotional ups and downs with extra sass, mood swings and eye roll. Basically, I’m just along for the ride. Sometimes it’s a great trip – he’s sweet, funny, cuddly even. I’m a cool mum and he’s actually appreciative and fun to be around.
Other times he’s a grumpy, ungrateful little turd. Oh, and I’m also literally the worst human being in the world and hanging out with me is (in his words) “actual dog water”. Yes, ladies and gents. Actual dog water.
So, clearly, I am NO help to this poor woman and her question about her son. But luckily Aussie mum and writer, Jo Eberhardt came to the rescue. She penned a reply that is so spot on that it puts our tweens’ behaviour into a whole new light.
When you nail it, you nail itโand Jo, well she nails it.

The tween brain explained
She starts:
My first son is eleven and a half right now. (Iโve been informed that the half is important.) I donโt claim to know the best way to talk to your son about this โ Iโm only an expert on my own children โ but I can tell you what I said to my son, and you can take from it anything that you feel is helpful.”
Jo explains how she opted to talk to her son while in the car, just him and her. It meant they would have half an hour, they’d be in a confined space (he couldn’t escape) and that they wouldn’t have to look directly at each other, making it easier to avoid accidental confrontation and to encourage vulnerability.
The conversation went like this:
Weโve talked a lot about puberty over the last couple of years, havenโt we? I just wanted to check in and find out if youโve got any new questions.โ
โNo,โ he said.
Okay. Well, let me know if you do. But I was thinking about things over the last few days, and I know Iโve been pulling you up a lot more on your tone of voice and the way youโve been speaking to people. Yeah?โ
โYeahโฆโ
โWell, it occurred to me that I really messed up.โ
โWhat do you mean?โ
The instructions are for a child’s brain
Well, Iโve spent all this time talking to you about the way puberty changes your body, and what to expect as you go through the changes, but I completely forgot to talk to you about whatโs going on in your brain right now.
Puberty is the time when your brain grows and changes more than at any other time in your life โ well, except for when youโre a baby, perhaps. Your brain grew and developed so quickly when you were little that by the time you were about five or six, your brain was almost as big and powerful as an adultโs brain.
But hereโs the thing. Even though your brain was super powerful, the instructions were for a childโs brain. And all the information about building an adultโs brain was a bit โฆ letโs say fuzzy.
So your brain did the best it could, but it didnโt really know what kind of person you were going to be back then, or what shape brain you were going to need.
Now we come to puberty. Not only is your body being transformed from a childโs body to an adultโs body, your brain has to be completely rewritten from a child’s brain to an adultโs brain.โ
It takes a lot of energy to completely rewrite a brain. Thatโs one of the reasons you get tired quicker at the moment โ and that, of course, manifests in you being crankier and less patient than normal.”
Adult amygdala, child frontal cortex
The other thing is that one of the first parts of your brain that gets super-sized to be like an adult is the amygdala. Thatโs the part that controls your emotions and your survival instincts. You know how weโve talked about fight/flight/freeze before, and how sometimes our brains think that being asked to speak in public is the same level of threat as being attacked by a sabre tooth tiger?โ
So, the thing with puberty is that all of a sudden youโve got an adult-sized amygdala hitting all your emotion buttons and your sabre-tooth tiger buttons.
See, the last part of your brain that gets rewritten is right at the front of your head. Itโs called the frontal cortex. And thatโs the part of your brain thatโs good at decision making and understanding consequences.
So youโve got this powerful adult amygdala hitting you with massive emotions, but youโve still got a fuzzy child frontal cortex that canโt make decisions or understand consequences as quickly as the amygdala wants you to. It pretty much sucks.โ
โSo itโs not my fault?โ

Tweens and puberty
It’s pubertyโs fault your brain works the way it does. But that doesnโt mean itโs not your responsibility to recognise whatโs going on and change your actions. Itโs not easy, but itโs not impossible, either.
Your feelings are your feelings, and theyโre always okay. But you get to choose your actions. You get to choose what you do with your feelings. And, when you make a mistake, you get to choose to apologise for that mistake and make amends.โ
Jo then goes on to explain to her son that, while puberty sucks for him, it’s also confusing for those around him.
If itโs confusing for you living inside there, imagine how confusing it is for me, when I only see your actions.ย
Sometimes Iโm going to get upset at things you do because I donโt understand whatโs going on in your head. Sometimes Iโm going to forget that youโre halfway to being a man, and accidentally treat you like a child.
Sometimes Iโm going to expect more from you than youโre able to give. This is my first time parenting someone through puberty, and Iโm going to make mistakes.
So can I ask you a favour?
Can you just keep telling me whatโs going on in your head? The more we talk, the easier it will be for both of us to get through this puberty thing unscathed. Yeah?โ
โYeah,โ he said.
So, did the conversation work?
Jo explains,
It didnโt completely stop him speaking disrespectfully to me. It didnโt completely stop me forgetting that heโs not my little boy anymore. But it opened the lines of communication.
It gave us a language to use.
And, together, weโre muddling through this crazy puberty thing, and Iโm completely confident that heโll come out the other end a sweet, wonderful young man.”
If you’ve got a tween who is starting to give you attitude, we recommend having this conversation and seeing if it helps. Fingers crossed it does!
