If both parents are bilingual, what language will the child speak when he/she is born?

Question

For example, you have both parents speaking Polish and English. If a baby was born, what will his or her language be? Does it depend on the location of your birth?

Will the child be bilingual? How does it work?

Answer 1

Language needs to be learned, it isn’t inherently known when a baby is born and grows up. So it will speak whatever language is likely most dominant in the home because it learns through observation of parents speaking.
