Ask a neuroscientist when childhood ends and you will not hear 18. The legal age of majority and the biological age of a mature brain are two different numbers, and the second one is closer to 25. That gap explains a lot of the behaviour we label as reckless in our early twenties: the part …

Reading readiness is not a single switch that flips at a specific age — it is a gradual build-up of multiple skills, from letter recognition …
Most parents remember the first tooth — that tiny white speck poking through at around 6 months. But the second big milestone, losing those baby teeth, catches many families off guard.
