My daughter Elisabeth has apparently reached an important developmental milestone: she's now climbing on the counters and taking everything out of the cabinets (especially in the bathroom) and leaving it in a jumbled heap in the counter or in the sink. That used to be Catherine's job, but she's moved beyond that stage.
Catherine is now interested in cooking. She just made "hot cocoa" out of water, milk, cherry jam, and salt. She pronounced it "yucky". So then she was on her way to mix up a new and improved batch. . . .
I'm afraid the answer to the titular question is "never". Please say it's not so.
