The \"why\" phase is how they're actively making sense of the world and testing out their growing ability to talk and think.\n\nThe sources I have don't cover how long this specific questioning phase lasts or what drives it developmentally, so I can't give you a precise timeframe. What I can tell you is that curiosity at this age is completely normal and worth encouraging — it's them doing exactly what they need to do at 3.\n\nIf the constant questions feel overwhelming, it's okay to set a friendly boundary (\"We can talk about five more whys before dinner\"), but there's no need to worry that this is anything other than typical development.","sources":"[{\"pmid\":\"guideline-6c685144b337\",\"title\":\"CDC — Developmental Milestones (Part 3 of 4)\",\"journal\":\"CDC Clinical Guidelines\",\"year\":\"2023\",\"url\":\"https://www.cdc.gov/ncbddd/actearly/milestones/index.html\",\"score\":0.72}]","thread_json":null,"topic":"cognitive-development","view_count":0,"created_at":"2026-08-25T02:04:38.634Z"}
