What Is ABA Therapy for a Toddler?
Applied behavior analysis (ABA) is a scientifically validated approach to understanding and changing behavior. For an 18-month-old, ABA therapy focuses on building foundational skills like eye contact, joint attention, imitation, and early communication. Sessions are play-based and child-led, using positive reinforcement to encourage desired behaviors. A Board Certified Behavior Analyst (BCBA) designs and oversees the program, while Registered Behavior Technicians (RBTs) often deliver direct therapy. ABA is not a one-size-fits-all program; it is tailored to your child's unique strengths and challenges.

Why Early Intervention Matters at 18 Months
The brain develops rapidly during the first few years of life. Early intervention for autism spectrum disorder (ASD) can significantly improve outcomes in communication, social skills, and adaptive behavior. Research shows that children who begin ABA therapy before age 3 often make greater gains than those who start later. In Maryland, early intervention services are available through the Maryland Infants and Toddlers Program (Part C of IDEA), which provides evaluations and early intervention services for children from birth to age 3 who have developmental delays or disabilities. Even without a formal diagnosis, you can request an evaluation if you have concerns about your child's development.
Signs That May Prompt an Evaluation
- Limited eye contact or social smiling
- Lack of babbling or gesturing by 12 months
- No single words by 16 months
- Loss of previously acquired language or social skills
- Unusual repetitive behaviors or intense fixations
What to Expect in ABA Sessions for an 18-Month-Old
At this age, therapy almost always occurs in natural environments such as your home, daycare, or community settings. Sessions are short-often 1-2 hours, several times per week-and built around play. The BCBA will identify specific goals, such as requesting a preferred item, imitating sounds, or tolerating a diaper change. Parents and caregivers are actively involved; you may be asked to practice strategies between sessions. Data is collected on every target skill to track progress and adjust the plan.
Common Goals for an 18-Month-Old
- Social engagement: Responding to name, sharing enjoyment with others
- Communication: Using gestures, vocalizations, or simple signs to request
- Imitation: Copying actions like clapping or waving
- Play skills: Functional use of toys, turn-taking
- Self-regulation: Crying less, transitioning between activities

Costs, Insurance, and Medicaid in Maryland
ABA therapy can be expensive, with hourly rates ranging from $60 to $150 depending on the provider and whether services are delivered by a BCBA or RBT. Fortunately, Maryland law requires many private insurance plans to cover autism treatment, including ABA, under the state's autism insurance mandate. This includes plans regulated by the Maryland Insurance Administration. Coverage often requires a diagnosis of ASD from a qualified professional and a prescription or referral from a physician.
Maryland Medicaid (HealthChoice and other programs) covers ABA therapy for eligible children under the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit. Parents should verify that the provider is enrolled in Medicaid and accepts their specific managed care organization. The Maryland Infants and Toddlers Program may also provide some ABA-related services at no cost if your child qualifies based on developmental delay.
How to Get Started with Insurance
- Obtain a formal ASD diagnosis from a developmental pediatrician, child psychologist, or qualified specialist.
- Request a referral or prescription for ABA therapy from your child's primary care provider.
- Contact your insurance company to confirm coverage, session limits, and in-network providers.
- If using Medicaid, check that the ABA provider is enrolled with your managed care organization.

Mistakes to Avoid When Starting ABA Early
Waiting for a Formal Diagnosis
You do not need a definitive autism diagnosis to start early intervention. Maryland's Infants and Toddlers Program can evaluate your child without a medical diagnosis. Early ABA strategies can also be implemented while waiting for a comprehensive evaluation.
Choosing a Provider Without a BCBA
ABA should always be designed and supervised by a BCBA. Some agencies employ RBTs without adequate oversight. Ask whether a BCBA will assess your child, write the plan, and conduct regular supervision.
Overlooking Parent Training
Effective ABA empowers parents to reinforce skills throughout the day. Make sure the provider offers parent training and coaching. You are your child's most important teacher.
Ignoring the Medical Necessity Requirement
Insurance companies require documentation of medical necessity. Work with your provider to ensure goals and progress are clearly documented. Without this, coverage may be denied.
