We do but none of the scary stuff. Our daughter does not like anything scary. We decorate for fall too.. hay bales, corn stalks, mums... for halloween we have the big light up pumpkin blow molds with faces. We also have small light up pumpkin faces that we use to light up the front walk way. We string orange and purple lights around our front deck.
Several years ago we found wood cut outs of jack o lanterns, black cats, ghosts and bats, we painted them and display them in the windows. We have small cutsy halloween knick knacks and stuffed pumpkins/jack o lanterns that we display in the livingroom, staircase landing, etc.
