jen; You mentioned hiding the toy when they are done playing with it. If I leave out their dingely bird, then it apparently becomes "old hat" to them and they will not play with it as hard nor as often. But, whenever I bring one (or two) of them in from the grocery store, all that is necessary is to inadvertantly make the little bell ring and Fawn and Chris come, seemingly from anywhere. and immediately want to play with it. I have to hide the toy when they are not watching, otherwise, they will find it and retrieve it, and begin dragging it all over the house.
