Baby Infant learning languages (Bilingual) with toys to improve IQ cognitive behaviour


Language development in infants is a fascinating process that sets the foundation for a child's cognitive, emotional, and social growth. Research suggests that exposing your baby to more than one language can have significant advantages in enhancing their cognitive skills and overall intelligence. In this blog post, we will explore the benefits of bilingual toys and activities, backed by scientific research, and provide you with practical tips for incorporating them into your baby's daily routine.

The Science Behind Bilingualism and Cognitive Development

Studies have shown that children raised in bilingual environments tend to develop superior cognitive skills compared to their monolingual peers. According to a study by York University, bilingual children exhibit enhanced executive function abilities, such as problem-solving, attention, and memory (Bialystok, 2001)1.

Another study found that bilingual children outperform monolingual children in tasks requiring cognitive flexibility, the ability to switch between tasks and mental sets (Barac & Bialystok, 2012)2. These findings suggest that exposing your baby to bilingual toys and activities can provide a cognitive boost, laying the foundation for a higher IQ.

Bilingual Toys to Encourage Language Development

To make the most of the benefits of bilingualism, consider incorporating these bilingual toys into your baby's daily playtime:

  1. Bilingual Storybooks: Reading to your baby in different languages can help them recognize and differentiate between sounds and words (Kuhl, 2004)[^3^]. Look for bilingual storybooks or translate your favorite stories to another language for added exposure.
  2. Talking Toys: Interactive toys that speak in multiple languages can teach your baby new vocabulary while reinforcing the connection between sounds and meanings. Examples include talking stuffed animals, language learning tablets, and electronic flashcards.
  3. Language Learning Apps: Introducing age-appropriate language learning apps can help engage your baby in interactive bilingual play. Many apps focus on teaching basic vocabulary, pronunciation, and sentence structure through fun games and activities.

Activities to Boost Bilingual Language Development

In addition to bilingual toys, you can engage your baby in the following activities to support their language development:

  1. Sing Bilingual Songs: Singing is an excellent way to introduce your baby to new words and sounds. Incorporate songs in different languages into your daily routine, and don't be afraid to make up your own lyrics.
  2. Bilingual Playdates: Arrange playdates with families who speak different languages. This will provide a natural environment for your baby to be exposed to different languages and cultures.
  3. Language Immersion Programs: Participate in local language immersion programs for babies and toddlers. These programs often include bilingual playgroups, storytimes, and other activities designed to promote language development.


Introducing your baby to bilingual toys and activities can significantly enhance their language development and boost cognitive skills. By providing a stimulating and diverse linguistic environment, you are setting the foundation for your baby's future success in learning and problem-solving. Remember that consistency is key, so make bilingual play a regular part of your baby's daily routine.
