Winter break camp runs indoors and outdoors on the same day, so the goal is layers your child can manage without help.
Pack a base layer and a sweatshirt they can tie around their waist, closed-toe athletic shoes with real tread, and a labeled water bottle they actually like drinking from. Add a packed lunch plus two snacks — kids burn through more than parents expect during the competition block.
Label everything. The single biggest lost-and-found category every week is unlabeled hoodies, followed closely by water bottles.
Finally, apply sunscreen before drop-off even in January. Outdoor field blocks still add up to a couple of hours of sun exposure.
