Constructing proper speaking since the very beginning
Speaking is one of the more complex human tasks because it involves not only muscular coordination but also several mental processes conducted simultaneously such as interpretation, recognition and expression, thus it's not a surprise that it takes up to 2 years to develop a comprehensive, coherent language and even up to last years of primary school to achieve a proper, adult way to speak.
However the language development is quite variable among different kids due to several factors such as cognitive maturity, environment and even personality, and even when at the end almost all humans beings will achieve an acceptable linguistic development, each one will do it at an individual speed.
Despite the aforementioned, many parents are concerned about their kids linguistic development and would like to find a way to "accelerate" it. The fact is that there's no reason to force your kid to develop a proper language faster than he/she is doing but there are several strategies to facilitate language acquisition since the very beginning.
Of course there are critical issues requiring professional attention, i.e. a kid who does not speak by the second year of life might have a sort of hearing impairment or neurologic problem affecting language development but these are not the commonest cases.
Most of children will develop proper language sooner or later and as parents we can increase their odds to achieve a rich, coherent vocabulary as well a good linguistic development on a natural way through the following hints:
1. Speak to your baby normally.
Many parents change their voice tone, wording or articulation when talking to their little ones in order to "speak like a baby" and even when cute, this is not the best approach because the linguistic pattern to be followed by the baby will be the "baby speaking" instead of a normal linguistic expression.
Certainly doing so time to time won't harm your baby's linguistic development and will be cute for both of you, however try to speak to your little ones on a normal way as much as you can. They are following all your patterns constantly, including the way you speak, so begin with the example.
2. Read them a lot
The best way to increase vocabulary and develop strong linguistic skills is reading. At the very beginning, when too young, your baby perhaps won't understand what are you reading to them but you will be introducing your little one on the reading experience through your example; additionally he/she will learn the differences of tone and modulation, something useful later on the life.
When older, your kids will enjoy to read not only stories but also all kind of books, including religion, science, literature and so on. Be sure to read with your kids on a daily basis and make pauses to explain the meaning of new words and concepts. It's not necessary to read an entire chapter every day in fact, just a couple of page daily will be enough.
3. Limit TV time
TV has nothing wrong but there's no interaction, most of time the kid is passive receiving information without no feedback, so even when some TV shows could add extra value to your little kids linguistic development, try to limit the total daily TV time to no more than a couple of hours.
4. Explain your kids everything around them
On the car, or walking on the street, the best way to teach vocabulary to your kid is talking about what you are seeing together. There's plenty of topics, from cars colors to different bird species around there. The possibilities are infinite as well the chances to help your little one to acquire a rich vocabulary.
5. Avoid improper speaking
If you cut word, your pronunciation is not good and wording and phrasing are improper, your kids will probably speak that way sooner or later. Remember you are the model for all their behaviors, including speaking, so talk the way you wish they do.
Finally if you think there's still something missing or there's any trouble, find professional support at school or development center in order to evaluate if your concerns are well based or if there's nothing to worry about, after all there's no limit when we talk about our kid's well being.
