Make a "lasting impression."
On a warm day, go outside and have your children (and anyone else who's game) place their hands and feet into a shallow tub of colorful, nontoxic paint. Spread out a roll of butcher paper, and have everyone press their hands and feet onto it, leaving their prints behind. Label each handprint and footprint with the person's name, the date, and special message to Mom, and allow your collective masterpiece to dry. Try this activity again next year, and see how much bigger some hands and feet have become!
