What to Expect in Your Child’s First ABA Session

Starting ABA (Applied Behavior Analysis) therapy is a big step, and as a parent or caregiver, it’s completely normal to feel a mix of excitement, hope, and maybe even a little anxiety. You want your child to thrive, and you might be wondering: What exactly happens during the first session? Let’s walk through what you can typically expect.

Building Trust

The first session is all about connection. Your child’s therapist will focus on building rapport—getting to know your child through play, conversation (if applicable), and observation. This stage is crucial because trust is the foundation for progress in ABA therapy. Don’t worry if it looks like “just playing”—this is an intentional part of the process!

Therapists might bring in toys, games, or activities that match your child’s interests. They’ll follow your child’s lead, engage in preferred activities, and avoid placing demands right away. This helps your child feel safe and comfortable in a new environment.

Assessment in Action

Your therapist may begin probing certain skills—things like matching objects, identifying body parts, or following simple instructions. This isn’t a test; it’s a way to see where your child is starting from.

Introducing Reinforcement

One of the most important tools in ABA is reinforcement—rewarding desired behaviours to increase the chance of them happening again. During the first session, the therapist will begin figuring out what motivates your child. Is it bubbles? Stickers? Trampoline? High-fives?

These reinforcers help keep your child engaged and make learning feel like fun. Don’t be surprised if you see the therapist offering small rewards after successful attempts at responding, participating, or even just engaging in a new task.

Parent Involvement

Depending on the setting (home, clinic, or school), you might be encouraged to sit in or observe the session. Some therapists will talk you through what they’re doing, while others may offer a recap at the end.

Feel free to ask questions or share information about what works for your child—your input is incredibly valuable. You are part of the team!

It’s Okay if It’s Not Perfect

Your child might be shy, tired, or unsure during the first session. That’s okay. Progress in ABA is built over time, not in one day. The therapist’s job is to meet your child where they’re at and support them at their pace.
