The earliest months of speech vary from person to person, usually 3-4 months for babbling, 6 months for understanding names, 9 months for imitating sounds, and 12 months of age for expressing simple words. Language development is related to the normal development of the brain, throat muscles and the perfection of hearing. Usually, at 3-4 months, infants can babble, imitate sounds at 9 months, and call their parents unconsciously at about 8-9 months. Around 1 year old, they can point out the names of hands, eyes, and simple objects, and around 1.5 years old, they can express some simple words and phrases. In addition, the time to speak is related to the environment and education. If you communicate with your child more and encourage pronunciation, the corresponding language skills will develop faster. It is normal for infants to speak within the normal time frame, either early or late. If the overall development of the infant is normal, parents should pay attention to good care, communicate more with the baby to promote the baby’s language development, and if necessary, need to go to the pediatric department of the hospital for evaluation.
