If you’re considering teaching your children more than one language at home, it helps to be able to sort the myths from the facts.

Dad is at the sink washing dishes when he feels a tug on his pants:
Running over to the dining room, Alex meets her mum clearing the last of the dinner plates off the table:
You don’t need to speak Spanish to understand that what’s going on here is more than a request for a biscuit. Alex is one of a growing number of children whose home is a real-world classroom for learning to speak, read and write more than one language.
In the cities and suburbs around the country, the sounds of Vietnamese, Arabic, Cantonese and many other languages are becoming more and more common. More and more multilingual families in Australia are facing a tough question – should my child learn more than one language, or only English?
In the example above, the answer is simple – Alex would learn both. Although her parents are fluent in both languages, dad is more comfortable with English and he uses it most of the time. For mum, Spanish is the language of her family, her culture and her heritage, a connection that she wants to pass on to her daughter.
In this country, there are lots of different views about the increasing numbers of bilingual children. A closer look at research suggests that teaching children more than one language at home has its own set of challenges and rewards.
There are many reasons to teach children multiple languages when they’re young:
But as the number of bilingual children has grown in Australia, so have the myths about how learning two languages affects children. Have you ever heard that bilingual children are more prone to language disorders, such as using the wrong word? Or that bilingual children have trouble communicating in both languages? Do bilingual kids struggle more with reading and writing?
There’s another benefit to teaching children to speak more than one language at an early age. Some studies suggest that bilingualism might help children develop certain attention skills sooner. ‘Selective attention’ is the ability to focus on important details while ignoring distracting and misleading information. It’s something bilingual children do a lot as they learn to filter out words from one language when speaking in another.
As already mentioned, learning two languages requires more practice than learning one. And that leads to some potential challenges for children in bilingual households.
The first is that it might take more time to develop a large vocabulary in each of the languages. Studies have shown that bilingual children tend to have somewhat smaller vocabularies in each language than classmates who speak only one language. But the reason is simple – they need to learn new words in both languages, instead of just one. That doesn’t mean they know fewer words.
The second challenge is that bilingual children may trail English-only classmates when it comes to specific language tests, at least in the early grades. One research study of nearly 1000 bilingual children showed that they tended to score lower on some oral language tests. But language tests aren’t the whole picture – when it came to talking to others and understanding them, bilingual children did well in both languages. And, as with vocabulary, the differences that showed up on the language tests tended to disappear in later grades.
For any family facing the question of teaching their children more than one language, the answer is simple – do what feels right to you.
There’s growing agreement among researchers that learning two or more languages – while adding some specific challenges – doesn’t hurt a child’s development. In fact, it might help develop important mental skills and open up a world of opportunities later in life.
Are you wondering how to help your child learn two languages? Here are some ideas to keep in mind.
