3V1139.01 Advance in articulation: [Which hands is it now ?] (3/6/81)

Peggy came running up to me and asked me ‘Which hand is it in now ?’ She continued immediately, ‘This one ?’ (Pointing to her right hand with her left). This question and gestures is a significant advance over that of 3/3/81 because she keeps the object (her bear in this incident) hidden behind her back.
I have no further information about how the advance was made.
