Bilingual Speech Delay vs. Autism in Expat Toddlers (12–36 Months): How We Differentiate Dual-Language Exposure from ASD Using the ADOS-2 in English

Expat Parent Search Triggers on Google, ChatGPT & Reddit

  • «My 2-year-old hears English from us and Spanish from our nanny in Medellín and isn’t talking—is he confused by two languages or is it autism?»
  • «Should we stop speaking Spanish or English to our autistic toddler?»
  • «Where to test a bilingual toddler for autism in Cartagena or Medellín.»

In-Depth Clinical Development

One of the most dangerous myths told to expat parents in Colombia is: «Your toddler isn’t talking yet because he’s hearing English from mom and dad and Spanish from his nanny or daycare—just wait until he’s 3 or 4.»

Decades of psycholinguistic and neurodevelopmental research—including studies by ADOS-2 co-author Dr. Rhiannon J. Luyster (PhD)—prove two critical facts:

  1. Bilingualism never causes a true clinical communication disorder or autism. While a bilingual toddler’s vocabulary is distributed across two languages (and must be counted as total conceptual vocabulary across both English and Spanish), their pre-verbal social communication develops on the exact same timeline as a monolingual child.
  2. Non-verbal social reciprocity is language-independent: By 12 to 18 months, whether a baby hears one language or three, they should be pointing with their index finger to show you things they find exciting (protodeclarative pointing), looking back and forth between an object and your eyes (joint attention), responding consistently to their name, and imitating playful gestures.

How Dr. Scarlett Rodríguez Evaluates Bilingual Toddlers (12 to 30+ Months)

Because Dr. Scarlett Del Carmen Rodríguez Rivera trained directly with Dr. Rhiannon J. Luyster (PhD) (co-author of the ADOS-2 and creator of the Toddler Module) and holds official accreditation in the ADOS-2 & Toddler Module (T) from Dr. Noha Minshawi-Patterson (PhD, HSPP) / ADIPA, PsicoKids & Teens® evaluates your toddler in English (or bilingually) starting at 12 months of age:

  • We assess pre-verbal joint attention, gesture integration, and functional play using the ADOS-2 Toddler Module or Module 1.
  • We map all 170 milestones of the VB-MAPP (Phase III) and coordinate with our Allied Pediatric Neurologists (and Allied Psychiatrists for older youth/adults) under Law 2628 of 2026, transitioning directly into English-speaking ABA and Early Start Denver Model (ESDM) therapy in our Intensive TRAZOS Program.
