Three critical periods
The development of children's oral English goes through three key periods: infancy, infancy and 3-4-year-old infancy. Parents should seize these periods and provide strong support for their children's oral development.
Views of foreign scholars
Some foreign scholars believe that it is a critical period for language development from 2 years old to adolescence. This period is very important for children's language development. Parents should guide their children and provide more opportunities for their oral development.
Research by domestic experts
At home, some experts also pointed out that 2 ~ 12 or 14 years old is the key period to master speech. If we miss this opportunity, it will become more difficult to learn the first language. Parents should seize these critical periods to help their children develop better.
