Children’s growth and development has individual differences, as long as it is within a certain range, it is normal. Babies who speak early and grow teeth early, as long as other growth and development indicators are normal, is a healthy baby, it does not matter whether it is good or not, and there is no direct relationship with the IQ.
Babies usually erupt around six months, some babies teething later, not more than a year old are normal, if the delay in teething, need to go to the stomatology department in time to clarify the cause of the disease, give calcium and other symptomatic treatment.
Babies begin to learn how to say simple words, such as mommy, daddy, etc. Some babies are slower in language development and can express themselves in simple sentences around one year of age. If they have not learned to pronounce words after one year of age, they need to seek medical attention to identify the cause of delayed language development and intervene promptly.
There is no direct relationship between babies’ early speech and teething and IQ. Intellectual development is affected by multiple factors such as genetics, nutrition, environment and acquired education.
