hand over hand
Using a pencil, trace the outlines of your hands (right and left) onto a sheet of paper. Then, trace the outlines of your child's hands onto the same sheet of paper. It's perfectly fine, even recommended, that the lines intersect. Then, have your child color in (using crayons or colored pencils) the individual shapes any way their imagination inspires them. Do this as many times as you like on different sheets of paper, changing the placement of your hands on the sheet. Pick your favorites and hang them prominently (might look nice framed).
