When I picked up Hannah from school today, 1 of her afternoon teachers told me that Hannah really helped her out today.  3 other little toddlers from her class were banging on a door in the classroom while the teacher was trying to quiet them down.  Her attempts wern't working when Hannah went over to each 1 of them and tapped them on their shoulder, put her finger over her mouth and said "shh" and some kind of baby talk the teacher couldn't understand and the other kids actually listened to her and stopped what they were doing.  She said it was really sweet and very helpful.
