Safe and Sound Protocol Guidelines for Autistic Children

Where do you start, and what does the first week look like?

Start with Connect. Every child starts there, regardless of age, diagnosis, or how the referral was worded. Connect is unfiltered, gentle, and does not require headphones. It can play through a small speaker while your child draws, does a puzzle, or sits quietly near you.

Five to ten minutes is a full session. That is not a warm-up. The filtered pathway, Core, is listened to in the same short sessions, and a full round unfolds slowly over roughly one to two months. There is no daily minimum to hit and no streak to keep. If you miss a day, you return where you left off. Progress does not reset.

The single most important thing to carry into the first week is this: less is more. A child who gets two good minutes and then signals they are done has had a successful session. Stopping early is good pacing.

1. Begin with Connect Unfiltered, no headphones required, can play through a speaker. This is where every child starts.
2. Keep the session short 5 to 10 minutes per day. Watch the child, not the clock. If they signal they are done before that, honour it.
3. Create a calm container Sit nearby. Do something quiet yourself. The child does not need to engage with you, but your regulated presence matters.
4. Move to Core only when settled Core is the filtered pathway and needs over-ear headphones that are not noise-cancelling and not earbuds. Move to it only after Connect feels easy and familiar.
5. Pace the whole round slowly A full round takes roughly one to two months for most children, sometimes longer. Slower pacing is not a sign something is wrong.

What does your child do while listening, and what should you avoid?

The protocol works best when the nervous system is neither bored nor overloaded. Quiet, hands-on activities are ideal. Drawing, colouring, simple Lego or building blocks, a calm craft, gentle play with a familiar toy. These give the body something to do without competing with what the ears are processing.

Screens are worth avoiding during a session. Not because of a strict rule, but because screens tend to pull the nervous system in a direction that works against what the audio is trying to do. Vigorous exercise, rough play, or anything that ramps up activation is also better left for after the session, not during.

You do not need to sit facing your child or make conversation. Being in the room, doing something calm of your own, is enough. Polyvagal theory proposes that a child's nervous system reads the cues coming from the adults around them, a concept Porges describes as co-regulation. That means your own settled state is not background noise. It is part of the mechanism.

What does disorganisation look like, and what do you do about it?

Some children move through SSP without much visible change between sessions. Others show what looks like a step backward: more tired than usual, clingier, irritable in the afternoon, sleep shifting, or briefly more meltdowns. This is not unusual, and it does not mean the protocol is harming your child.

Polyvagal theory would describe this as the nervous system reorganising. The body is working. What matters is the degree. Tender is fine. A child who needs an extra cuddle that evening, sleeps longer, or is a bit more emotional for a day or two is within the range of what many families notice and move through.

When the response is bigger than that, the right move is straightforward: shorten the next session, return to Connect if you had moved to Core, slow the overall pace, or pause entirely and wait a few days. There is no deadline. Coming back after a pause is not starting over.

If your child is distressed during a session, stop the session. Not at the end of the track. Stop. A session that ends early because the child needed it to end is a session that protected the nervous system, and that is exactly what you want to do.

What is the goal here, and what is SSP not trying to do?

SSP is designed to support your child's comfort and capacity. The idea behind it, rooted in polyvagal theory, is that a nervous system spending less energy on defence has more available for connection, communication, and learning. That is the frame.

It is not a compliance tool. It is not designed to produce eye contact, reduce stimming, or make your child easier to manage in public. If someone has suggested SSP for those reasons, that is worth a conversation with the referring professional. The goal is a child who feels safer in their own body and in the world around them.

On the question of what SSP cannot do: it is not a replacement for occupational therapy, speech therapy, or any medical or psychiatric care your child receives. It sits alongside those, not instead of them. And for children with severe sound sensitivity, active seizure disorders, or certain neurological conditions, SSP needs medical clearance before starting. The screening on the site asks about this directly.

Two peer-reviewed studies from Porges's research group, published in 2013 and 2014, found reductions in auditory hypersensitivity and improvements in behavioural organisation and spontaneous social engagement in children with autism spectrum diagnoses. Those are the published findings. They are real, and they are also from small samples in supervised clinical settings. Honest parents deserve that full picture. ^1,2

When is self-serve the right choice, and when is guided support worth it?

Self-serve SSP works well when a professional who already knows your child, a therapist, an OT, a developmental paediatrician, has recommended it and is part of the picture. That means someone who can answer your questions when a session goes sideways, who can help you read what you are seeing, and who can tell you whether to slow down or pause. You are the one sitting with your child. They are the thinking partner.

If nobody is currently guiding you and you are relying entirely on what you can read online, the guided option is the safer starting point. Naadham, the guided tier offered here, includes weekly live support so you have a place to bring what you are noticing.

One more thing worth naming: the parent as a co-regulator is not a small detail in this protocol. Porges's original research describes the calm, present adult as structurally necessary for the intervention to work. That means your own nervous system matters too. A parent who is anxious about whether they are doing this right, or who is running on empty, is a harder container to be inside. Knowing that about yourself is useful. If you need support alongside your child, that is worth building in from the start.
