Think in categories: explore, build, create, rest. Pack a small tarp, silicone molds, squeeze bottles, painter's tape, a magnifier, chalk, and a zip pouch of rubber bands and paper clips. Include extra socks for sandy sneakers and a bright ribbon to spot your umbrella from afar.
Choose sturdy finger foods that tolerate heat and sand: sliced apples, snap peas, trail mix without chocolate, hummus jars, and frozen yogurt tubes that become cooling packs. Label water bottles, schedule sips per activity, and pause mid-morning for a joyful, shade-side picnic storytelling break.
