Answer:
critical period.
Step-by-step explanation:
Generally speaking, speech learning develops during the first two years of the baby's life. During this time, the baby will be able to identify and name some objects. From 2 years old, they can start to form short sentences and simple questions. The development of your language gradually increases until you are 5 years old when, as a rule, you can already express yourself in a much more direct and clear way. The first four years of a child's life is a critical period for language development, however there are special situations that many children go through and which in one way or another may affect the development of their speech.
