The sooner you start, the better.
Sign language should be introduced as soon as possible, so that the baby can contact sign language during the language sensitive period, which will help the baby to better understand and remember.
Teaching from the basic needs of life
Starting from the basic needs of life such as "eating", "drinking" and "diaper", it is easier for the baby to understand and remember. At the same time, parents should also interact with their babies more so that they can master sign language better.
Enhance parent-child tacit understanding
Sign language education can not only improve the baby's IQ, but also enhance the tacit understanding between parents and children. When a baby can't express himself in words, a simple sign language gesture can help you quickly understand his needs and improve communication and understanding between parents and children.
