Teach children to check their clothing for stains when they take it off....if the knees of the pants look ok......if there is no lunch or supper spilled on the front of the shirt.....then it is clean enough for another wear. Have them put the item back in their drawer or hang it on the handy hooks that you have installed in their bedroom. As we teach our children from little on up that each member of the family has their part to play, we are teaching them valuable life skills.
