WTBH-
maybe you could tell the girls that you thought of something you would like- maybe you could make some cookies(even the ready to bake-slice and bake -type) and they could decorate them for you as you do something else (sprinkles or some cake icing and little deco bits are not too messy or difficult), and they could wrap them in a box or something (provide bows, stickers, etc- they will be proud of their lovely creations) and surprise you. that would make good memories for them, and for you too. it is so beautiful how children want to give to the ones they love.
