Buried Alive

One of G's and D's favorite games is to bury the other one under a mountain of stuffed animals. The act of burying one another under the fluffy, cuddly, odd looking stuffed creatures that fill their bedroom seems to produce great fits of giggles -- much to my delight. Well, at least it does until one or the other gets frustrated and busts out, which generally includes a well placed fist to the other child's head. Oh! The joys of parenthood!
Did I happen to mention that G is an exhibitonist and it seems to be IMPOSSIBLE to keep clothes of any sort on her. Any ideas about how to keep her clothes on, short of duct tape? (Which I have sconsidered recently since she strips everyehere!!!)
