Bilingualism

   This is the ability to speak more than one language at a time. The first is simultaneous learning of two languages which happens when the language used at home is different from the one used in the community or at school. The other type is sequential or successive. This happens when a child has one established language before learning a second language, whether in preschool or later. Some children and adults, usually learn a second language through school or language classes.
    Proactive inhibition occurs when a language that was learnt previously, interfere with the language presently being learned. Retroactive interference on the other hand occurs when what we are learning actively interfere with what we have learnt before. In the case of retroactive inhibition, some people cannot make a sentence in their mother tongue without bringing in another language like English language. It affects the concept in the child's learning strongly. Multiplicity of language the child is exposed to not helpful in language development. It is advisable that when children are learning two languages simultaneously, parents needs to work out language strategies that emphasize boundaries between the languages.
    They should provide the right environment and talk to all children in the same way, not talking to one in one language and and another in another language. To avoid problem of bilingualism in language development, parents are advised not to force their children into it if it really does make them unhappy. They should avoid mixing the language in the same conversion. This is counterproductive in language development. It is also advisable that parents avoid abrupt changes in how they talk to children under six.
   However, researches have shown that bilingualism can pose no problem to a child who has no language learning disability. A child finds it easier learning more than one language before the age of twelve. A child can benefit from bilingualism because it is good for his overall linguistic and cognitive development. When a child has learnt the first language well, probably the native language, he can successfully learn a second language.
