How can parents and guardians foster english language and vocabulary development at home? how might this be affected if the parents'/guardians' primary language is not english?

As early as possible, the guardians at home must speak in English to naturally put the babies' at ease with it. It is much easier to teach young people. If the parents' primary language is not English, then the child would have learn later in school. Or worse, he would have to acquire English lessons especially if needed at work.
