The subject of language learning of children in bilingual families is considered in this paper. The author discusses practical problems and provides examples from his own family situation in which his children learned French, English, and German. The possibility of language mixture is discussed and the author presents some tentative conclusions about the usage of a particular language in a particular situation. If the situation is a natural one, it is likely to motivate the child to use the language of the situation. If the parents do not interfere or force the child to speak a given language in a given situation, the overall linguistic development of the child is likely to be normal. If the parents inconspicuously lead the child into natural contexts in which the probability of language switch is high, the full language learning potential of the situation will have its effect upon the children.
