Teachers' role in the conflicts of 2- and 3-year-olds was examined in Dutch and Finnish child care centers.

Two types of equally used teacher interventions were distinguished: mediating strategies and high power strategies. Teachers employing mediating strategies based their intervention on the nonverbal strategies of young children to de-escalate territorial conflicts. (Author/KB)
