Some sibling fun will occur naturally, but you can help it along, too. Break out a new box of sidewalk chalk and have them create a crazy new monster together. Let them use the video camera to make a movie. Have them team up together for a surprise project to give to a grandparent. However you do it—family bike rides, board games, making cookies, teaming up against Mom with the water guns, whatever—find ways to help your kids have fun together and strengthen the bonds that connect them.
