About baby＇s language development by the time stages accordingly. Paying special attention to the efforts for the parents or caregivers. Infants receive more talking education and speak earlier. Most parents can hardly wait for their baby to say its first word and communicate with their baby. From about 2 years old, the child should be able to use simple phrases, retell simple story and even to sing song. Parents play an important role in this stage. By the 3 years children begin to use most of function words rather than omit them. And acquisition for the second language will help children＇s language development. The children have a gift for learning language.展开更多
