DDs are well past that stage but it's one of their favorite memories that they mentioned ever so often. For a few years I ran a Keepers of the Faith girls group that met every other Friday afternoon. It always seemed to turn into a sleepover with anywhere from 1-4 girls spending the night with my dds. DH said he was always careful when going in to kiss them good night because he didn't know who was sleeping on the floor! Most of the time they took over the livingroom with air mattresses/sleeping bags/couch cushions on the floor. I just always made sure that the next day was a quiet day at home. Also, in order to spend the night, everything had to be straightened up and put away in the morning when they got up. Lots of fun memories!!
