Are children who talk early smart?

In the past two days, I have dreamed every night that I have grown up every day, one moment 8 or 9 months old, the other time I am a teenager, in short, I am talking to me in my dreams. I think of recently I often hear everyone say that Xiao Tian is only 2 months old, ah, oh, oh, want to speak, in the future, he must speak early, and he must be smart. At first, I was very happy to hear it, but then I felt a little bad, wasn't it that she was under pressure to prove that she was smart without knowing it, in case she spoke late, she would be called a stupid child? In fact, speech has long been smart, mostly the way old people speak, and in the current language, the IQ is high. However, the old man does not know that IQ includes many aspects, such as observation, memory, imagination, analytical judgment, thinking ability, adaptability, etc. The ability to learn language should be part of IQ, but only a small part. Many great scientists are not good at words, and a great physicist like Einstein could not speak at the age of three. Newton's childhood was also considered a dumb child. Therefore, the level of language ability does not represent the level of IQ. Of course, strong language ability is also an ability, and children who speak early may be suitable for learning language. It is understandable that many parents or grandparents want their baby to be smart, but it is not necessary to worry too much about their child's IQ. Some parents also like to show off that their children are smart when they speak, which also makes those children and parents who speak late under unfair public pressure, after all, parents hope that their children will not lose to others in all aspects. In fact, children's childhood should grow up happily, should not be hurt by the comparison atmosphere of adult society, and should not bear the pressure that they should not bear too early. I hope that our little day can talk early and communicate with us. So I've been talking to her every day since not long after she was born, but if she talks later than the other children, it's okay, I will still insist on talking to her, just let her know that Dad cares about her every day.
