Is the speech of bilingual children delayed?
It used to be suggested that bilingual children were a little slower learning to speak than monolingual children. This is no longer an accepted view. In any case, any such difference would be very small. A bilingual child whose speech is delayed (for example, if they have not said the first word by 18 months) should be treated exactly like a monolingual child. It is dangerous to think that the child’s speech is delayed because the child is bilingual. Bilingual children vary from one another just as monolingual children do — some will be early and some will be late speakers. But all children whose speech is delayed should be assessed by a doctor and (if necessary) a speech-language practitioner, because if the child is deaf, or if there is some reason for the speech delay, it should be dealt with.
