I have a dcg who needs some one to entertain her as well when my kids are sleeping. I have some special books and toys that she can play with only during the time she is on her own. I also have school time with her and we work on her letters, numbers etc. and then there is play dough. If she is not in the mood for any of this, I let her watch Leap Frog Letters video and do what I have to do around the house.
