Alphabet Coloring Pages - great idea for baby shower! Print all the letters on cardstock or heavier paper. Have guests color the pages anyway they like and sign a message for baby on the back. Have the pages laminated and bound into a keepsake book!
What a fun game! Make two dice: one with numbers, and one with colors. Roll the dice, then use dot stamps to make that number of dots in that color on your paper. My adaption would be to have the dice be a doubles dice to practice double math facts
