ABA vs ESDM for a 2-Year-Old: Which Therapy Is Right?
In short: ABA and ESDM are both evidence-based therapies for young children with autism, but they differ in approach. ABA focuses on breaking down skills into small steps using reinforcement, while ESDM is a play-based, developmental model that blends behavioral and relationship-based strategies. For a 2-year-old, ESDM is often recommended for its naturalistic, child-led style, but ABA can also be highly effective, especially when delivered early. Both are commonly covered by insurance and Medicaid.
Key takeaways
- ABA uses structured teaching and reinforcement to build skills; ESDM uses play and natural interactions in a child-led setting.
- ESDM is specifically designed for toddlers aged 12-48 months, while ABA can be adapted for any age.
- Both therapies are evidence-based and can improve communication, social skills, and behavior in young children.
- Insurance and Medicaid often cover both ABA and ESDM, but coverage varies by state and plan.
Understanding ABA and ESDM for Toddlers
When your 2-year-old receives an autism diagnosis, you may hear about two prominent therapies: Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM). Both are backed by research and designed to support young children, but they take different paths to reach similar goals. This guide will help you understand the differences, what to expect, and how to choose the best fit for your family.

What Is ABA Therapy?
ABA is a scientific approach that uses principles of learning and behavior to teach new skills and reduce challenging behaviors. For a 2-year-old, ABA often looks like structured play sessions where a therapist breaks down skills-like requesting a toy or making eye contact-into small, teachable steps. Positive reinforcement (like praise or a favorite activity) encourages the child to repeat desired behaviors.
Key Features of ABA for Toddlers
- Individualized: A Board Certified Behavior Analyst (BCBA) designs a plan based on your child's unique strengths and needs.
- Data-driven: Therapists track progress daily to adjust teaching strategies.
- Intensive: Many programs recommend 20-40 hours per week, though younger children may start with fewer hours.
- Parent involvement: Parents learn strategies to reinforce skills at home.
What Is the Early Start Denver Model (ESDM)?
ESDM is a comprehensive, play-based therapy specifically designed for children ages 12 to 48 months with autism. It blends behavioral principles (like those in ABA) with developmental and relationship-based approaches. Sessions are child-led, meaning the therapist follows the child's interests and uses natural play to teach communication, social interaction, and cognitive skills.
Key Features of ESDM
- Naturalistic: Learning happens during everyday activities like playing with blocks or pretending to cook.
- Relationship-focused: Therapists build strong, positive connections to motivate learning.
- Parent coaching: Parents are trained to use ESDM strategies throughout the day.
- Lower intensity: Typically 15-25 hours per week, with a focus on quality over quantity.

ABA vs ESDM: Side-by-Side Comparison
Philosophy and Approach
ABA is more structured and therapist-directed, while ESDM is child-led and play-based. Both aim to improve communication, social skills, and behavior, but they differ in how they get there. ABA often uses discrete trial training (DTT) where a therapist presents a clear instruction and reward. ESDM uses naturalistic teaching within play routines.
Age Appropriateness
ESDM was created specifically for toddlers and preschoolers, making it a natural fit for a 2-year-old. ABA can be adapted for any age, but some families feel the structured format is less suited to very young children. However, many ABA providers now offer naturalistic, play-based approaches that resemble ESDM.
Evidence and Research
Both therapies have strong research support. A landmark study by Dawson et al. (2010) found that children who received ESDM showed improved IQ, language, and adaptive behavior compared to those who received community interventions. ABA has decades of research showing effectiveness for a wide range of skills and ages.
Cost and Insurance Coverage
Both ABA and ESDM are often covered by private insurance and Medicaid, especially when prescribed by a doctor. Costs vary widely, but intensive therapy can range from $50,000 to $100,000 per year without coverage. Many states mandate insurance coverage for autism therapies, including ABA and sometimes ESDM.

How to Choose Between ABA and ESDM for Your 2-Year-Old
Consider Your Child's Personality
Some children thrive with structured, predictable routines (ABA), while others respond better to flexible, play-based interactions (ESDM). Observe how your child learns best-do they enjoy following a clear sequence, or do they prefer exploring freely?
Think About Family Fit
Both therapies require parent involvement, but ESDM places a stronger emphasis on coaching parents to integrate strategies into daily life. If you want a therapy that feels more collaborative and less clinical, ESDM might appeal to you.
Look at Provider Availability
ABA providers are more widely available across the United States, while ESDM is less common and may require travel or telehealth. Use a free matching service to find vetted, BCBA-led providers in your area who offer either therapy.
Practical Tips for Getting Started
- Get a diagnosis first: A formal autism evaluation from a developmental pediatrician or psychologist is usually required for insurance coverage.
- Ask about naturalistic ABA: Many ABA providers now offer play-based, child-led approaches that blend elements of ESDM.
- Start early: Research shows that early intervention (before age 3) leads to the best outcomes.
- Consider a hybrid approach: Some children benefit from a combination of both therapies, depending on their needs.
- Use a free matching service: ABA Care Near Me can connect you with BCBA-led providers who specialize in early intervention and accept your insurance.
Common Mistakes to Avoid
- Waiting too long: Don't delay therapy while you decide-start with one approach and adjust as needed.
- Ignoring your gut: If a therapy doesn't feel right for your child, it's okay to explore other options.
- Overlooking parent training: Both therapies work best when parents are actively involved.
- Assuming one size fits all: Every child with autism is unique; what works for one may not work for another.
Final Thoughts
Choosing between ABA and ESDM for your 2-year-old is a personal decision that depends on your child's needs, your family's values, and available resources. Both therapies are effective and can make a profound difference. The most important step is to start early and stay engaged. If you're unsure where to begin, a free matching service like ABA Care Near Me can help you find vetted, BCBA-led providers who will guide you through the process and ensure your child gets the support they deserve.
