Describe the action, not the person
Start with what you observed, not what you concluded about her. "The bathroom floor still had soap residue" describes a fact she can check and fix. "You're careless with cleaning" is a verdict, and most people respond to a verdict by defending themselves rather than listening for what to change.
Keep the sentence short and free of comparisons to other helpers or to how you'd do it yourself. The goal is a shared, checkable description of the gap between what happened and what you needed, not a judgement about effort or intelligence.
- Name the specific task and what was wrong with the result
- Skip words like "always" or "never" that turn one instance into a character trait
- Leave out comparisons to previous helpers or to your own standard
Say it privately, and pair it with the fix
Take the conversation somewhere the two of you can speak without an audience, even if that just means stepping into the kitchen for two minutes. Being corrected in front of your children or a visiting relative adds a layer of shame that has nothing to do with the actual task, and it tends to produce defensiveness instead of a fix.
Every correction needs a next step attached. If the folding wasn't right, show the fold once rather than only naming the flaw. If a cleaning product was used on the wrong surface, say which one belongs there instead. Feedback that stops at "this was wrong" leaves her to guess at the standard; feedback that ends with "here's what right looks like" gives her something to repeat.
Close the loop before you both move on
Ask a short question that confirms she understood, rather than assuming a nod means agreement, especially where language is still building. "Can you show me how you'll do it next time?" surfaces a misunderstanding immediately, while ending the conversation on your explanation alone leaves it untested until the next time the task comes around.
If the same issue keeps recurring across several days, that's no longer a single-moment correction; it's a pattern to bring into the structured weekly conversation, where you can look at cause, training and expectations together rather than repeating the same in-the-moment note.
