Spring is beautiful. Brighter mornings. Greener days. A world waking up again. But ask a family with young children what spring really brings, and the answer is often the same: sleep becomes more unsettled. And that is not a coincidence. When days are filled with more light, more sounds, and a body in constant activity, a child’s nervous system works harder. Nothing is wrong. They are simply alive and curious. But the body does not always know when to slow down on its own — and that is when parents notice the impact.
