I Stopped Comparing My Kids to Each Other (It Took 6 Months)

Let me tell you the sentence that made me realise I had a problem. It was a Tuesday evening, October, both kids at the dining table doing homework. My son — P5, the older one — was struggling with a long division question. My daughter — P3, the younger one — had just finished her sheet in fifteen minutes, all correct.

And I said it. Out loud. In front of both of them.

"See? 妹妹 finished already. Why can't you be more like her?"

My son didn't cry. He didn't shout. He just put his pencil down, very quietly, and stared at the table. And my daughter — this is the part that haunts me — my daughter looked guilty. Not proud. Guilty. Because she knew I'd just used her as a weapon against her brother.

That was the night I decided to stop. It took six months to actually do it.

Why it's so hard to stop

Here's what nobody tells you about sibling comparison: it's not a bad habit. It's an instinct. When you have two children in the same household, attending the same type of school, doing the same curriculum, the comparison data is right there. It's unavoidable. Your brain does it before you can stop it.

A 2023 survey by the Hong Kong Institute of Family Education found that 78% of parents with two or more children admitted to making verbal comparisons at least weekly. Weekly. And 62% said they knew it was harmful but "couldn't help it."

I was firmly in that 62%. I read the parenting books. I knew comparison damages self-esteem, breeds resentment between siblings, and teaches children that love is conditional on performance. I knew all of this. And I still did it, because in the moment — when you're tired, when homework is taking forever, when one child is flying and the other is sinking — comparison is the easiest weapon in your arsenal.

The six-month detox

I'm not going to pretend I found some magical technique that fixed everything overnight. I didn't. Here's what actually happened, month by month.

Month one: awareness. I started counting. Every time I made a comparison — out loud or in my head — I put a tally mark on a Post-it stuck inside the kitchen cupboard. The first week, I counted seventeen. Seventeen comparisons in seven days. Some were obvious ("Your sister got 95, why did you get 80?"). Some were subtle ("Interesting, 妹妹 didn't need help with this one"). Subtle is almost worse because nobody flags it.

Month two: substitution. When I caught a comparison rising, I replaced it with what I call a "same child" comparison — comparing the child to their own past performance, not to their sibling. Instead of "妹妹 finished faster," I tried "You're faster than last week." Instead of "Your sister got full marks," I tried "You improved by three marks from last time." This was mechanically difficult. The sibling comparison was always right there, easier, more vivid.

Month three: the backlash. My son noticed the change and actually tested it. He deliberately did badly on a worksheet and watched my face. He was waiting for me to bring up his sister. I didn't. He looked confused. This broke my heart and gave me hope at the same time.

Month four: separate conversations. I started discussing homework with each child individually, never together. This removed the comparison environment entirely. It took more time — two conversations instead of one — but it eliminated the trigger.

Month five: the relapse. Chinese New Year family dinner. My mother-in-law asked, in front of everyone, "So who got better results this term?" And before I could intervene, I heard myself say, "Well, 妹妹 did very well..." I caught myself mid-sentence. But the damage was done. My son heard the first four words.

Month six: the conversation. I sat both kids down and said something I'd never said before: "I used to compare you two and that was wrong. I'm sorry. You're different people and I'm going to talk to each of you about your own work, not each other's."

My daughter said, "I know, Mummy. It's okay." My son said nothing. But the next morning, unprompted, he showed me a maths question he'd figured out on his own. He hadn't done that in months.

What changed

I won't lie and say everything is perfect. I still catch comparison thoughts. The difference is that they stay thoughts — they don't become sentences anymore.

Here's what I've actually observed: my son volunteers more. He asks for help instead of hiding mistakes. He doesn't shut down when homework is hard — he just takes longer, and that's fine. My daughter, meanwhile, has stopped performing for my approval. She does well because she wants to, not because she's racing her brother.

The relationship between them has softened too. They argue about normal sibling things — who gets the remote, whose turn it is on the Switch — but the academic competition is gone. They're kids again, not competitors.

The one thing I'd tell any parent

You won't stop comparing overnight. Don't aim for perfection — aim for catching yourself. The Post-it tally was the single most useful thing I did. You can't fix what you can't see, and most comparison happens on autopilot.

And if your mother-in-law brings it up at dinner, change the subject. Quickly.
