If you can’t talk at around 1 year old you should be vigilant and seek prompt medical attention. Newborns can cry, babble at 3~4 months, speak simple words at about 1 year of age, pronounce plurals at 7 months of age, recognize family members’ special titles at 18 months of age, point out simple names and pictures at 2 years of age, recognize many kinds of objects at about 3 years of age, sing songs and describe simple scenarios at 4 years of age, begin to read at 5 years of age, and tell stories at about 6 years of age. When your child is late in speaking, you should be alert and seek medical attention to check the development of the brain and throat muscles as well as the sense of hearing, to identify the cause of the late speech, and to treat it in time to maximize the quality of life.
