How do you know when a therapist isn't working for your child? This guide covers green flags, red flags, how long to give a new therapist, and how to switch without losing ground.
Finding a therapist is hard enough. Figuring out whether the one you found is actually right for your child is a different problem—one that most families have to solve while already emotionally invested, financially committed, and exhausted from the search. Knowing what to watch for in the first weeks of therapy, and giving yourself permission to act on what you observe, is one of the more important skills in navigating care for a child with autism or attention-deficit/hyperactivity disorder (ADHD).
A reasonable window for an initial assessment is 6 to 8 sessions. Early sessions involve building rapport, completing assessments, and establishing baseline—clinical progress may not yet be visible. What should be visible is a therapist who is organized, communicative, and engaging your child in a way consistent with their needs.
If something feels wrong in the first two or three sessions, pay attention. Not every instinct needs 8 sessions to confirm.
A therapist who is the right fit explains their goals in terms you understand. They adapt to your child's cues—dysregulation, disengagement, resistance—rather than running a protocol regardless of what your child is doing. They communicate with you after sessions: what they worked on, what they observed, what you can try at home. They track progress and can tell you specifically what the data shows. And they treat your knowledge of your child as an asset.
Your child consistently refuses to attend. Some early resistance is normal—new environments, new people, disrupted routines. Persistent refusal that doesn't improve after several weeks is worth investigating. Your child is communicating something: anxiety, a personality mismatch, or sessions that are aversive in ways not visible to you. Ask the therapist directly how they're handling it and watch the answer closely.
Sessions feel identical week after week. Therapy should evolve. Goals should progress, new targets should be introduced as old ones are mastered, and the approach should adjust as the therapist learns more about your child. If every session looks the same month after month with no visible movement, that's a stagnation problem worth addressing.
The therapist can't articulate what they're working on or why. If you ask "what are you currently targeting and how are you measuring progress?" and receive a vague or deflecting answer, that's a significant concern. A competent therapist working from a clinical framework can answer this question specifically and clearly.
Little to no parent communication. For pediatric occupational therapy (OT), speech-language pathology (SLP), and applied behavior analysis (ABA), parent involvement isn't optional—it's how skills generalize from the therapy room to your child's actual life. A therapist who sends your child back to you with no feedback, strategies, or carryover activities is delivering incomplete care.
You feel dismissed when you raise concerns. You know your child. A therapist who responds to your observations with defensiveness or dismissal rather than curiosity is telling you something important about how they work. That dynamic rarely improves on its own.
The first therapist is not always the right therapist. Sometimes the mismatch is about personality, communication style, or approach rather than quality. Recognizing a poor fit and acting on it is not failure; staying in a poor fit because the search was hard is the more costly choice.
If you switch, a professional handoff—including a summary of what was worked on and what progress was made—helps the next therapist start from a stronger foundation.
Keeping notes on what you observe—session by session, provider by provider—makes these decisions clearer over time. What's Next Health's provider directory lets you log notes on each provider directly, so your observations are organized and accessible when you need them.

OT, PT, and speech therapy all serve different purposes. This guide explains what each addresses for autism and ADHD, how to determine what your child needs, and how to sequence when you can't start everything at once.
