First of all, we must consider whether the child has physical problems and dysplasia. It is best to take the children to the hospital for a detailed examination and make the next plan according to the examination results. Of course, if there are 2-3 generations in the family who have speech delay, and their babies have different language development levels except speaking late, parents don't have to worry too much. Some parents may see that other people's children can talk before they are one year old, while their own children are just babbling at the age of one and a half.
The newborn baby can only cry, but the progress of his pronunciation foundation is also quite obvious; 1 month began to "evolve" and some non-crying sounds appeared; At 5 months, with the continuous development of the vocal organs, more sounds will be made. Some pronunciations are close to those of adults, and they will be repeated in the future. The development of baby's language is related to the normal development of brain and throat muscles and the improvement of hearing. Newborns will cry, and babies will babble for 3 ~ 4 months. 6 ~ 7 months can understand others calling their names; 12 months old, able to understand and speak simple words.
In practice, due to individual differences, some babies' language develops earlier, and it is normal when they are over 4 years old; Some babies' language development is relatively late, and the language of 7-8 years old is completely normal. So 5-7 years old is a general age stage. Every baby grows up in a different environment. Some families are silent, don't like communication, and their babies have less opportunities to exercise.
