Sleep Talker

Jaydin was talking in her sleep today during her nap (she does this fairly often, but not all the time is it actual words we can understand over the monitor). First, I should say that she INSISTS on sleeping with her baby, Minnie, Elmo, her 3 blankets, and her favorite monkey. She's got quite the crowd at bedtime. Anyway, in her sleep she started making monkey noises then said "Monkey! Shh! I sleeping!" Then she went back to sleep. Dang monkey trying to wake her up. The nerve. Is this maybe a sign of multiple personality disorder?
