Updated October 2026. The first version of this post gave a “7-10 second window” and several other specifics that I could not trace back to the sources I cited. I rebuilt it from what the research actually supports. Where something is my own read, I say so.
You’ve asked your child to put their shoes on three times. They’re still standing there, absorbed in their LEGOs, like you haven’t said a word. So you ask again, louder this time, with an edge in your voice you didn’t intend.
It’s probably the most frustrating part of parenthood, and my biggest pet peeve. Every day like clockwork, I ask my kids what they want for breakfast. No answer. What are they doing? Anything that isn’t answering me. Is it because they hear me? No. Is it because they just don’t want to answer? Maybe. As annoying as it is, I get that, I’m the same way. Is it how I’m asking? When I’m asking? The list goes on and on in my head. Then the frustration hits, because truly, I’m trying to help you out, kid. The options are limited, they didn’t change from yesterday, and they know what there is... and yet, nothing.
I looked into this because I wanted to know what is actually happening in those few seconds, and what turned up was less tidy than the version I used to give parents. I could not find a study that says how many seconds a four-year-old needs before a command lands. What I found is a small set of findings on different questions, and a consistent hint that repeating the same ask does not buy us much. That is my synthesis, not a single result.
What the timing data actually says
The closest thing to seconds data is a study of 53 children between 2 and 10 (some referred to a clinic for noncompliance, some not), where researchers timed how long it took each child to start doing what they were asked. On average, children started in about six seconds, and 98 percent had started within 14 (Shriver & Allen, 1997). The children who were referred for noncompliance were not slower to start than the others. They just complied less often.
That is a behavioral study, not a brain study. It measures when children begin, not how long their brains take to process, and it comes from a clinic setting rather than your kitchen. Most children started within about six seconds, and nearly all within 14. The study cannot tell us why a child has not started by 10 seconds, so I would not guess at what is going on in their head.
Why one instruction at a time
Adults can hold around three to five things in working memory at once, not the seven you may have learned in school (Cowan, 2010). Children hold fewer. In one lab task, seven-year-olds held about one and a half items compared with about three for older children and adults. That was a visual memory task, not a spoken command, and it says nothing direct about four-year-olds.
Where it gets practical is a pair of studies on older kids. In 42 children aged 7 to 11, verbal working memory was linked to how accurately they followed spoken instructions across several tasks (Jaroslawska et al., 2016). And in a group of 52 children selected for low working memory, teachers described them as distractible and quick to lose track of what they were doing (Gathercole et al., 2008). Susan Gathercole, who has studied this for years, describes the classic example as a child who completes the first step of a longer instruction and then stops (Gathercole, 2008, The Psychologist).
So when you say “shoes, backpack, coat, meet me at the door,” you’ve asked for four things from a system that, in that 7-year-old lab task, held about one and a half. I can’t tell you what a four-year-old holds. I see this constantly, in my own house and in the parents I work with, and the research on school-age kids points the same way. One instruction is the safer ask.
Knowing the rule is not the same as doing it
Executive attention, the part that helps a child resolve competing pulls on their attention, is still developing through the preschool years. In a computer-based study of 4- and 6-year-olds, executive attention improved strongly between those ages (Rueda et al., 2005). A review of the broader literature puts reliable switching between tasks at around seven to nine, in lab switching tasks (Diamond, 2013). I originally told you four-year-olds have fully functional attention. They don’t, and the study I cited didn’t say that.
There is also a finding I keep coming back to. Toddlers around 31 to 34 months could state a rule better than they could act on it, and by 36 months the gap was gone (Zelazo & Reznick, 1991). That was a card-sorting task, so I’m not going to pretend it is a study of shoes. But it matches what I see, a kid who can tell you exactly what they’re supposed to be doing and still isn’t doing it.
What about repeating?
Here is what I can and can’t say. In a 1976 experiment with 32 mother-child pairs, repeating a command did not reduce noncompliance, while adding a mild negative consequence did (Forehand et al., 1976). In a small study of four preschoolers, repeating the instruction up to three times did not raise compliance (Wilder et al., 2012). Both are old or tiny, and neither tested a parent in a hurry or tested loudness.
I wrote in the first version that repeating “resets your child’s brain to step one.” I could not find a study that measured that. What I can say is narrower: repeating the same ask, with nothing else changing, did not help in the studies I found.
Absorbed kids may be harder to reach
Children aged 3 and 5 who had been watching a screen for a sustained stretch were harder to distract from it (Anderson et al., 1987). That was television, not LEGO, and the distractor was not a parent’s voice. My read is that a deeply absorbed kid is often not ignoring you so much as caught in what they are doing. That is my interpretation of the screen study, not something it tested.
You may have heard this explained through polyvagal theory, that a child’s nervous system “state” switches off their access to language. I’ve used that framing before. I’m going to be more careful now. Polyvagal theory is a model, and a group of 39 researchers recently published a paper arguing it is untenable (Grossman et al., 2026), which Porges has answered in print (Porges, 2026). I haven’t found a study showing that a child’s momentary play state reduces their ability to understand spoken language. A 2023 review describes caregiver and child states as influencing each other, though the authors note most of that work is correlational (Bornstein & Esposito, 2023). My read from practice is that a rushed, tense parent gets a different response than a settled one. That is clinical judgment, not a finding.
What I do, and what I’d try
This is my practice and not a protocol anyone has tested as a package.
Get close, and get their eyes or a nod before you speak. In my experience, a command from across the house to a child who is absorbed is the weakest version of the ask. Give one instruction, in plain words, and stop talking. Then wait, longer than feels comfortable (count it in your head, it runs longer than you think). In the timing study the average was about six seconds and nearly everyone had started by 14. I count a slow ten. That is longer than the timing data requires, so treat it as my habit, not a rule.
The clinical parenting program PCIT uses a five-second wait as part of its protocol, and I could not find where that number came from. One small study found a child complied better when the wait was shortened from 10 seconds to 5 (Wilder et al., 2012), so I would not treat longer as better.
If nothing has started, try a different version: closer, a different word, or walk over and help them begin. That is my practice, not something tested.
Three questions before you try again
Am I actually waiting? What is my child doing right now, deeply absorbed, wound up, or free? And what is my own body doing as I speak, because they are reading that too.
What I can’t give you here
I used to tell parents that neurodivergent kids need 15 to 20 seconds. I can’t find a source for that number, so I’ve taken it out. What I found instead is that in lab reaction-time tasks, children with ADHD were less consistent but not reliably slower on average once that inconsistency was accounted for (Kofler et al., 2013). That is lab data on ADHD only, and I found nothing either way for autism or language disorder. A single child who is consistently slow to respond, or who stops responding in specific situations, deserves a closer look than a blog post can give.
That’s not something a post, mine or anyone else’s, can map for you. On the free 30-minute discovery call we look at what is happening with your actual kid, and I tell you honestly whether I’m the right person to help. Book it here.
This explains the why. Whether it’s true for your specific kid is what the paid chat is for. Bring your real situation, I’ll answer it there.
