Bilingualism: Should I Teach My Child Two Languages?

If your child seems delayed in their speech and language skills, or has received a diagnosis such as Autism Spectrum Disorder, it is only natural to be concerned about the type and level of language input they are receiving. For kids with limited language, we are often concerned that too much input, or input in two or more languages, might be confusing and impede their progress. Research in this area has grown substantially over the past several years and the conclusions are surprising. 

What are the benefits to teaching my child two languages?

  • Improved communication with friends and family
  • Increased participation in cultural/community events
  • Improved language, social language, and pragmatic skills
  • Cross-linguistic transfer, or the ability to use the skills learned from one language towards the development of the other

What does current research say?

Increasing research in the field is changing long held beliefs regarding childrens’ language acquisition. Here are just a few examples:

  • Children with Down Syndrome who speak two languages score as well as children with the same diagnosis speaking just one language on English tests. 1
  • Children diagnosed with Autism Spectrum Disorder (ASD) who speak two languages demonstrate similar abilities to children with ASD speaking just one language. 2
  • Bilingual children with language delays learned English vocabulary faster when it was first taught in their native language than students taught vocabulary in English alone. 3

What if my child seems to be struggling?

It is easy to get concerned if your child appears to be falling behind their peers, or seems to lack vocabulary in either English or their home language. Keep in mind that differences in the development of the two languages are normal, and may even out over time.

Is learning two languages going to confuse my child?  Evidence from multiple studies demonstrates that children with and without language impairments are capable of becoming bilingual, and demonstrate skills at the same level as their monolingual peers. 4

What if my child is mixing vocabulary from their languages in sentences?   Individuals speaking two or more languages, both with and without disabilities, frequently engage in a behavior called code-switching , in which vocabulary words from one language may be included in a sentence that is in the other language. This is a normal process. Code mixing may be the result of a child “borrowing” a word from their other language that has no translation equivalent, that they have not had experience yet using in one language, or because or the context of the situation. 4

My child can’t pronounce words correctly in either language, is this a problem?

Even typically developing children as old as 7 years may demonstrate patterns of sound errors. These error patterns will be present across languages if similar sounds exist in both languages. If these issues persist late into childhood and interfere with your child’s ability to be understood by friends, family, teachers, and peers, it may be helpful to consult a Speech-Language Pathologist.

What can I do at home?

  • Engage in early literacy activities with your child in their first language, such as shared book reading. 5
  • Use the first language consistently with your child at home. 6
  • Model longer and more descriptive sentences in the first language. 6
  • Promote utilizing the home language in multiple environments through visits with family/friends who speak the language, watching television programs in the first language, and visiting community centers where the first language is widely spoken. 6

When a baby arrives earlier than expected, the first weeks and months can bring both joy and uncertainty. Families often leave the NICU or hospital with important instructions — but also many questions about their baby’s development. Parents may find themselves wondering: “Should my baby be rolling, smiling, or eating more by now?” These questions are very common for families of premature infants. Many concerns fall into a gray area between needing formal therapy and simply needing expert reassurance and guidance. At Progressive Pediatric Therapy, our Guiding Growth Program provides proactive developmental support for premature and medically complex infants — helping families understand their baby’s development while building confidence during the first year.

In a world filled with screens, typing, and digital learning, handwriting — especially cursive — is becoming less common in many classrooms. Yet handwriting remains one of the most powerful tools for learning. Writing by hand connects movement, memory, and meaning in ways that typing simply cannot. At Progressive Pediatric Therapy, our Cursive Handwriting Program helps children strengthen the physical and cognitive skills behind writing while rediscovering the joy of putting pen to paper.
