What's the reason the kid's not talking?

Clinically, some babies do not like to talk. In fact, this is also related to many reasons. First of all, the most important thing is that there is a certain relationship with heredity, that is, if the baby's personality is more introverted or the parents are also people of this personality, it may cause congenital babies to not like to talk. Of course, acquired factors are also very important, such as the baby's courage is relatively small, and frequent contact with almost all family members, rarely contact with strangers outside or children will also cause the baby's courage is too small and unwilling to talk. This requires parents to educate at home, talk more with the baby, and let the baby contact more people and things outside.
