DNA validates that all humans are biologically different from each other. So, when it comes to setting each other apart mentally, we also develop certain behaviors, habits, skills etc. at our own pace. This type of development is normally done from the time we are born until we are toddlers, typically around age three. One of the skills we learn is language because it allows us to communicate with other humans who share the same or similar language. While not everyone speaks a second language, in a globalized world like today, it is certainly not unusual for someone to speak more than one language. Those who do are either simultaneous bilinguals—learn two languages at once—or are sequential bilinguals—learn a second language after learning the first one. Since language is an acquired skill, we all vary in language development, meaning facing language delay is to be expected in some toddlers. For toddlers raised in bilingual households, who is more likely to face language delay and who faces it to a greater extent – simultaneous bilinguals or sequential bilinguals? Before beginning to talk about the extent of language delay among simultaneous and sequential bilinguals, it is important to distinguish what type of language delay is being discussed in this particular context and why it is important to look out for language delay in any child. The Merriam-Webster dictionary defines “delay” as “a situation in which something happens later than it should.” So, if a child is facing a delay in language, he has not reached the expected milestone of his age group. These milestones are how speech therapists determine whether or not the delay in language is severe or mild, and what approach should be taken to correct it.
A delay can occur depending on external and internal factors. Internal factors would be speech disorders, such as speech apraxia, dysarthria, and other
