Children who are bilingual before the age of 5 are significantly more likely to stutter and to find it harder to lose their impediment, than children who speak only one language before this age, suggests research published ahead of print in Archives of Disease in Childhood.
The researchers base their findings on 317 children, who were referred for stutter when aged between 8 and 10.
All the children lived in Greater London, and all had started school in the UK at the age of 4 or 5.
