Most middle schools serve lunch before noon, and research shows that kids this age need steady fuel every three to four hours. By late afternoon, their energy and focus start to slide. A practical after-school snack helps stabilize mood, support homework time, and keep evenings from unraveling. Here are some simple, affordable ideas that work well for preteens.
