One person: One language and bilingual children
from Psychology Today
A well-known approach used with children who are acquiring two languages simultaneously is for each parent to use his or her own language with their child. Thus, for example, parent 1 will use Spanish and parent 2 English. This is known as the one person — one language strategy or OPOL. The strategy has probably been around since the beginning of intermarriages between people belonging to different language groups. In recent times, however, its onset has a precise date: 1908. It was in that year that a baby boy, Louis, was born to the Ronjat family in France.
