A bilingual baby is learning two languages while at the same time learning to tell the difference between them. “It is possible that since learning two languages at once requires more information-processing efficiency, the infants have a chance to rise to this challenge by developing skills to cope with it,” the researchers theorised.
For this study, bilingual babies were defined as having at least 25 per cent exposure to a second language and monolingual babies were defined as having at least 90 per cent exposure to a first language, namely English.
So, start now, speak different languages to your baby and watch her grow!
