Finally, An Answer For Every "Why?"
Somewhere around age 3, most kids' brains hit a real developmental leap: they start building cause-and-effect reasoning, and it shows up as a nonstop stream of "why" questions sometimes over 100 a day. It can feel endless, but researchers who study it (Chouinard, 2007) describe it as an "Information Requesting Mechanism" a built-in tool kids use to gather knowledge exactly when they need it.
Here's the part most parents don't know: a 2009 study (Frazier et al.) found preschoolers were measurably more satisfied nodding, agreeing, asking real follow-ups when adults gave them an actual explanation instead of a vague brush-off like "because I said so." Kids who don't get a real answer are more likely to just keep repeating the question. They're not being difficult. They're still waiting for the answer.
