If you only pick three: read Low-Demand Parenting by Amanda Diekman for the day-to-day approach, read the Declarative Language Handbook by Linda Murphy for how to speak so your child can hear you, and bookmark the PDA Society website for everything else. Below is the longer list — books, courses, communities, podcasts, and apps — with honest notes on who each one is best for.
Essential Books
Declarative Language Handbook — Linda K. Murphy
The foundational text on speaking in observations and invitations rather than commands and questions. Murphy is a speech-language pathologist, and the book is short, concrete, and immediately usable. It wasn't written specifically for PDA — its roots are in supporting social learners more broadly — but it has become the reference for PDA families because demand-free communication is the core of the approach. Pair it with our declarative language examples for PDA-specific scenarios. Her follow-up, the Co-Regulation Handbook, is a worthy second read.
Low-Demand Parenting — Amanda Diekman
Diekman is an autistic adult and parent of a PDA child, and this is the most practical book on actually running a low-demand household: dropping demands deliberately, deciding what's essential, and letting go of the rest without guilt. If your family is in burnout or your child is in school refusal, start here.
The Family Experience of PDA — Eliza Fricker
Fricker's illustrated take on daily PDA family life is validating in a way prose can't always manage — many parents say it's the first book that made them feel seen rather than instructed. Light to read, genuinely useful to hand to relatives who "don't get it."
Courses and Practitioners
At Peace Parents — Casey Ehrlich
Casey Ehrlich's courses, membership community, and free podcast focus specifically on PDA. Her "accommodation-first" framing helps parents understand why their child's nervous system responds the way it does, and the community aspect matters — PDA parenting is isolating, and talking to parents living the same reality helps more than most interventions.
inTune Pathways — Kristy Forbes
Kristy Forbes is an autistic/ADHD educator and parent of PDA children. Her courses and writing center the child's internal experience and are especially strong on school struggles, burnout, and reframing behavior as communication.
Organizations and Communities
- PDA Society (UK) — the most established PDA organization anywhere: free guides for parents and schools, helpline-style support, and the research hub. Start here for credible, shareable information.
- PDA North America — growing hub for US and Canadian families, including their useful primer on declarative language and PDA, plus an annual conference. Helpful for finding PDA-aware professionals in a region where recognition is still patchy.
- Peer communities — At Peace Parents' community, and PDA-specific groups on Facebook and Reddit. Quality varies; the good ones are the fastest way to feel less alone.
Podcasts
- At Peace Parents Podcast — short, PDA-specific episodes; the natural free entry point to Ehrlich's work.
- Tilt Parenting (Debbie Reber) — broader neurodivergent parenting, with standout PDA-relevant episodes including a great interview with Linda Murphy on declarative language.
Apps
The app landscape for PDA specifically is thin — most "autism parenting" apps are schedule and routine tools that need heavy adaptation for demand-avoidant kids. Our app, Gentle Ally, is built for PDA caregivers: it generates personalized declarative phrases in the moment. For the wider landscape — visual planners, AAC, and where each fits a PDA family — see our honest roundup of the best apps for PDA and neurodivergent parenting.

Frequently Asked Questions
What's the best first resource for a parent new to PDA?
Start with the PDA Society website for a grounding in what PDA is, then read Low-Demand Parenting by Amanda Diekman for the practical day-to-day shift. If communication battles are your biggest struggle, make the Declarative Language Handbook by Linda Murphy your first book instead.
Is PDA a recognized diagnosis?
PDA is not a standalone diagnosis in the DSM-5 or ICD-11. It's most often described as a profile of autism, and recognition varies by country and clinician — better established in the UK, growing in North America through organizations like PDA North America. Many families pursue an autism assessment with a clinician familiar with the PDA profile.
Are there good free PDA resources?
Yes. The PDA Society and PDA North America websites are free and comprehensive, At Peace Parents runs a free podcast alongside its paid courses, and many practitioners share substantial free content. Books and courses add depth, but you can get a real foundation without spending anything.
