Yesterday my little girl (16 months and counting) showed her caregiver just how good her comprehension is already:

Both she and the other little girl (J, 12 months) at the caregiver’s were eating a piece of bread. That is, my girl had already finished hers and was eyeing that of little J. More than eyeing actually, and when the caregiver saw her with J’s bread, she was told “No, J’s bread remains in J’s hand.”
Next time she looked, J was holding her piece of bread, but my little girl was holding her hand so that she could eat the bread.

Should she be punished? She obeyed the caregiver’s orders, after all.
