Do you mean she is talking in her sleep??

Maybe she is to over stimulated before bed time.. My ds does this and i mean you think he is awake.. He gets up plays and walks around and talks to us as if we are the people in his dreams.. very scary but i cant stop him lol unless i tie him to the bed..

what i do know is take him into quiet time before bed cause ds is on meds to help him sleep it only takes 40 minutes to kick in and his out so i take him into the room and read books or even discuss what his done for he day and what he wants to do the next day..
maybe letting her express herself before bed will take everything out of her mind..

and i could just imagine how tired you would be cause i am the same i have to follow him around to make sure he doesnt fall down the stairs or climb up the cupboards
