Paul Bright, founder and dadWhen your child says their sibling is the favourite, the defence arrives fully loaded.
You remember the lift you gave them yesterday, the extra half-hour you spent on their homework, the identical birthday budgets and the argument where you were much harder on the other child. You have receipts. Enough receipts, in fact, to build a small paper fort and wait inside until the accusation passes.
I don't think you should use them.
Proving that you love your children equally answers the question in your head. It may not answer the one your child is actually asking.
Two accounts of the same family
A three-year study asked parents and two adolescent siblings about affection and discipline in their family. Parents rated whether they treated one child differently from the other. Each child rated their own treatment relative to their sibling.
Their accounts didn't always match. The gaps between what parents reported and what their children perceived were small to moderate on average, but they weren't meaningless. Some patterns of perceived favouring and disagreement were linked with warmth and conflict later. The details were fussy: results varied by parent, child and birth order. This was an observational study of 381 predominantly white, working and middle-class, two-parent families with adolescent children. It doesn't tell us who was objectively right, and it isn't a formula for every family.
That is exactly why I find it useful.
The disagreement wasn't treated as bad data to be deleted. It was part of the family relationship.
Your intention matters. What you actually did matters. Your child's experience matters too. Those are three different things, and forcing them into one verdict called "favourite" makes the conversation almost impossible.
Find the comparison hiding inside the accusation
"You love her more" sounds like a claim about the whole family. Usually, the next useful question is much smaller: what happened that made it feel true today?
A second study gives us a practical way to narrow it. Researchers asked adolescent siblings about different treatment across six areas: chores, privileges, conflict, affection, punishment and time. The young people also rated how fair they thought that treatment was.
That distinction matters. Different isn't automatically unfair.
An eleven-year-old may stay up later than a seven-year-old. A child who is struggling with school may need more homework help. One child may have a support need that changes what is realistic for them. Mathematical equality can be deeply unfair when the children, circumstances and needs aren't equal.
But a justified difference can still look like a mysterious private deal when nobody explains it. And sometimes the child has spotted a pattern you missed.
So don't audit the entire childhood in one sitting. Pick apart the category.
Is this about time alone with you? Who gets help fastest? Who gets the stricter rule? Who is expected to cope because they are older or "easier"? Who gets interrupted? Who gets forgiven? Who gets affection in the form they actually notice?
Ask each child separately, not as a family courtroom where siblings have to argue over who is loved correctly. The American Academy of Pediatrics recommends listening carefully, asking about the child's feelings and reflecting back what you heard to check you understood. You don't have to agree with a child's conclusion to understand the comparison underneath it.
That might sound like: "I don't agree that I love your sibling more, but I want to understand what has felt unfair. Was there a particular moment you were thinking about?"
Then listen long enough for the global charge to become a specific event.
Repair the thing you can name
Once the complaint is concrete, you are no longer wrestling a fog bank called "favourite". The answer can now be one of three things: a pattern, a reason, or a single missed moment.
First, the pattern. Perhaps one child gets more one-to-one time because their activities happen to suit your schedule. Perhaps the child who protests loudly gets a rule negotiated while the quieter child gets the original answer. Perhaps you keep asking the older one to understand because it is faster than helping the younger one wait.
If the pattern is unfair, repair that pattern. Name it without turning the conversation into a confession about your entire identity as a parent. Change the rule, make time, apologise for the missed moment, or stop handing the same child the invisible job of always coping.
Second, the reason. Explain it plainly, while leaving room for the child to dislike it. "Your brother gets more help with reading because he needs more help with reading" is an explanation. It doesn't require the other child to cheer.
Third, the missed moment. One painful incident may be sitting underneath a much larger word. You can repair the incident without demanding that your child withdraw the accusation immediately. Feelings don't update like a spreadsheet after one corrected entry.
What you shouldn't do is promise perfect equality from now on. That turns family life into a running invoice and trains everyone to inspect each transaction. The aim isn't to make every minute, rule and reward identical. It is to make differences understandable, needs visible and genuinely unfair patterns easier to correct.
Put away the receipts
Being accused of having a favourite hurts because it collides with something you know about yourself: you love your children, and you are trying.
Keep knowing that. Just don't make proving it the child's first job.
The accusation may be inaccurate, exaggerated, based on a reasonable difference, or pointing straight at something you need to change. You cannot know which while you are reading out the family accounts.
Put away the receipts. Find the comparison.
