I have three kids and they all started talking very early. Many new parents ask me if it is better for babies to talk early or not? Is it something they are born with?
Firstly, I personally do not think this is hard-wired. There is no timer in the brain of a baby that says, now you are 1 years old, you should start saying words. It is very much dependent on the stimulation the baby gets from their environment.
Secondly, babies who can communicate early are very easygoing babies.
Because they can express themselves and are not as frustrated as a baby who uses sounds to communicate.
