Studies of Type 6 Child Bilingualism

Bilingualism Second Edition by Suzanne Romaine (1995)

Burling’s Study (1959)
It is a child who heard only English until he was about 17 months. After that, he went to India and Garo was his dominant language there because there were only monolingual Garo speakers in his environment. When he was nearly 3 years, he had clearly separate vowel systems, but he never acquired the consonant systems. Replacements of the English consonants were used for the Garo ones.
