It depends on how old your child is, but you will want to label any spare clothes, water bottles, lunchboxes, shoes, jackets, backpacks, and other personal items. The label does not need to be fancy; it could be as simple as a piece of masking tape, or you can even write directly onto an inside tag with a permanent marker. If you use a permanent marker, place a cloth or towel under the label before writing your child's name so that it doesn't bleed through to the clothing.
