I had an appointment and had to bring my son, hes 17 months old. When we where in the waiting room he took a crayon another kid around his age was playing with the kid started to get up set, So i picked up my son walked over to the other little boy, took the crayon my son had taken and handed it back to him. Then I told my son its not nice to take things others are playing with, gave him his toy car and sat him down. (he cryed for like 1 min because i took the crayon)
