Teaching your preschooler a few extra words could be setting them up for a lifetime of academic success, a study suggests.
A study of almost 900 four-year-olds found those with larger vocabularies were more engaged with teachers and other children when they later started education.
Researchers tested the youngsters' abilities in the autumn and then checked in on them when they started school the following spring.
The researchers say their findings show how even small differences in a child's early years can have a large impact on their chances of academic success.
They also hope the findings will help teachers identify children with smaller vocabularies when they start school for more support with their learning.
