Key Points:
- ‘Behind’ and ‘developing differently’ are not the same thing and the distinction matters enormously for how a child is supported, understood, and helped to grow.
- Developmental milestones are averages, not deadlines: They describe the midpoint of a wide normal range, and a child who falls outside that range in one area may be flourishing in others.
- The pattern matters more than any single milestone: A therapist looks at the whole child how they engage, regulate, communicate, and play not just whether they said their first word by 12 months.
- Different does not mean less: Many children who develop differently go on to build rich, connected, capable lives especially when their unique developmental profile is understood and supported early.
It usually starts at a playdate or a well-child visit. Another parent mentions that their two-year-old is already putting three-word sentences together, or the pediatrician pulls out a developmental checklist and starts asking questions that make your stomach drop. And suddenly you are doing the mental math comparing, calculating, worrying.
Is my child behind?
It is one of the most common questions we hear from families across New Jersey from parents in Montclair and Maplewood, from families in Freehold and Flemington, from caregivers in Camden and Cherry Hill. And it is one of the most important questions to answer carefully, because the word ‘behind’ carries enormous weight. It implies a race with a fixed finish line. It suggests that your child is losing ground they should have already covered. It can make a parent feel like they or their child have already failed somehow.
A DIR/Floortime therapist sees it very differently. This blog is an attempt to share that perspective not to dismiss real developmental concerns, but to offer a more nuanced, more accurate, and ultimately more useful framework for understanding how your child is growing.
The Problem with ‘Behind’: What Developmental Milestones Actually Mean
Developmental milestones the ages by which most children walk, talk, point, and play are among the most misunderstood pieces of information in pediatrics. Parents encounter them in baby apps, parenting books, and well-child visit handouts, and they almost universally interpret them as deadlines. If my child is not walking by 12 months, something is wrong.
But that is not what milestones mean. Milestones are statistical averages derived from large population studies. They describe the age by which roughly 50 percent of children in a sample achieved a particular skill which means 50 percent of children achieved it later. The ranges around those averages are wide, and they account for enormous variation in genetic background, family environment, bilingual language exposure, temperament, and opportunity.
Consider walking. The average age for independent walking is around 12 months, and the typical range extends from 9 to 15 months. A child who takes their first independent steps at 14 months is not ‘behind.’ They are at the far end of typical and they will almost certainly be running by 18 months with no lasting consequence whatsoever.
Now consider language. The average age for first words is around 12 months. But first words can appear anywhere from 10 to 14 months and remain squarely within the typical range. By 24 months, most children have 50 or more words and are combining them into two-word phrases but the range here is even wider, and children in bilingual households, children with older siblings who ‘speak for them,’ and children who are simply later verbal bloomers may reach these benchmarks several months after their same-age peers with no underlying developmental concern.
None of this means that developmental milestones are useless. They are genuinely important screening tools, and significant or multi-domain delays warrant prompt evaluation. But a single missed milestone in isolation a child who is not yet walking at 13 months, or not yet combining words at 24 months is rarely the whole story.
What ‘Developing Differently’ Actually Looks Like
When a DIR/Floortime therapist talks about a child developing differently, we are describing something more specific than simply being a late talker or a cautious walker. We are describing a child whose developmental profile shows a pattern, a constellation of strengths and challenges that reflects a fundamentally different way their nervous system is organized and processing the world.
These children are not running the same race more slowly. They are running a different race on a different track, one that requires a different kind of map to navigate successfully.
The Profile of a Child Who Is ‘Behind’
A child who is developmentally delayed behind in the traditional sense typically shows a fairly uniform pattern of slower development across multiple domains. Their motor skills, language, social engagement, and cognitive abilities are all somewhat delayed relative to their age, but they tend to progress through developmental milestones in the expected sequence, just at a slower pace. Given appropriate support and time, many of these children catch up substantially.
A child with a global developmental delay might, for example, be functioning across the board at the level of a child six to twelve months younger. Their social smile came late, their first steps came late, their first words came late, and their pretend play is emerging on the later side. But the sequence is intact they smiled before they babbled, they babbled before they said words, they said words before they combined them. The architecture of development is the same; the pace is different.
The Profile of a Child Who Is Developing Differently
A child who is developing differently, the profile most often seen in children with autism, sensory processing differences, ADHD, or other neurodevelopmental variations shows something more complex and more uneven. Their developmental profile is not uniformly slow. It is asynchronous.
These children might show stunning abilities in some areas alongside significant challenges in others. A four-year-old who can read chapter books fluently but cannot sustain a back-and-forth conversation for three exchanges. A three-year-old who assembles 100-piece puzzles with ease but dissolves into a full meltdown when asked to shift from one activity to another. A six-year-old who can recall and recite entire scripts from movies but struggles to use language to tell you what they want for lunch.
In New Jersey families we work with, the asynchronous profiles we encounter most frequently include:
- Advanced rote memory or visual-spatial skills combined with significant social communication delays, the child who can identify every dinosaur by species at age three but does not yet wave goodbye
- Strong gross motor development running, climbing, jumping combined with significant fine motor challenges and very limited use of gestures or pointing
- Impressive vocabulary paired with language that functions more like labeling or recitation than genuine two-way communication the child who knows the word for everything but asks for nothing
- Hyperlexia reading words fluently well before kindergarten alongside significant difficulty understanding the meaning of what is read or using language to share ideas and feelings
- Rich imaginative inner world elaborate pretend play themes visible in solo play alongside a consistent inability to include or respond to another person within that play
These profiles are not ‘behind.’ They are different. And that distinction changes everything about how we approach support.
Why the Distinction Matters for Treatment
This is not a semantic debate. Whether a child is ‘behind’ or ‘developing differently’ has real, practical implications for the kind of support they need and the approach most likely to help them flourish.
A child who is globally delayed will often make excellent progress with approaches that essentially repeat and reinforce developmental experiences more exposure, more practice, more time in a structured, supportive environment. These children are following the typical developmental roadmap; they just need more fuel and a gentler pace.
A child who is developing differently needs something else entirely. They need an approach that starts by understanding their unique neurological architecture, how their sensory system is organized, what their emotional regulatory capacity looks like, what motivates and engages them, where their developmental strengths can serve as scaffolding for areas of challenge. Applying a one-size-fits-all developmental curriculum to a child with an asynchronous profile often produces frustration for the child, discouragement for the family, and limited meaningful progress.
This is precisely why the DIR model (Developmental, Individual Difference, Relationship-Based) is structured the way it is. The ‘Individual Difference’ component is not a footnote. It is the recognition that every child’s nervous system is unique, and that effective support must begin with a deep understanding of that specific child’s sensory profile, motor planning abilities, processing style, and emotional regulatory patterns.
Before a single Floortime session begins, a DIR therapist builds a detailed picture of who this child is not where they fall on a developmental percentile chart, but how their individual nervous system shapes the way they experience and engage with the world. That picture becomes the foundation of everything that follows.
The Six Functional Emotional Developmental Levels: A Different Way to Measure Growth
One of the most powerful gifts the DIR model offers families is an alternative to milestone-based measurement. Rather than tracking whether a child has hit a specific behavioral benchmark by a specific age, DIR/Floortime tracks progress through six Functional Emotional Developmental Levels (FEDLs) each one describing a capacity for engagement, connection, and thinking that builds on the one before it.
Understanding these levels reframes the entire question of ‘behind’ versus ‘different’ because they describe not what a child can do, but how a child experiences and relates to the world around them.
Level 1: Self-Regulation and Interest in the World
Can the child calm themselves enough to engage with their environment? Can they take in sensory information sights, sounds, textures, movement without becoming overwhelmed or completely shutting down? A child who is still working on Level 1 may appear disconnected, frequently overwhelmed, or lost in their own internal experience. This is not a child who is ‘behind.’ This is a child whose nervous system has not yet found its footing in the sensory world and Floortime builds that footing, one co-regulated experience at a time.
Level 2: Engagement and Relating
Does the child show warmth and interest in the people closest to them? Do they light up when a parent enters the room, seek physical closeness, share pleasure through eye contact and smiling? A child who is at Level 2 but has not yet moved beyond it is present in the relationship they want connection but they do not yet know how to initiate or sustain it. This is a child developing differently, not a child who is behind. The desire is there. The roadmap is not yet complete.
Level 3: Two-Way Purposeful Communication
Does the child engage in back-and-forth exchanges; gestures, sounds, words, or actions with intention and purpose? Can they open a circle of communication (by reaching, vocalizing, or acting) and respond when the circle is returned to them? A child who reaches Level 3 has crossed one of the most significant developmental thresholds there is. Whatever their age, whatever other challenges they carry, the capacity for intentional back-and-forth communication is the foundation on which everything else is built.
Levels 4 Through 6: Complex Communication, Emotional Ideas, and Logical Thinking
The upper three levels build progressively more complex capacities: sustained problem-solving interactions with others (Level 4), the ability to represent emotional experience symbolically through pretend play and language (Level 5), and the integration of feelings and logical thinking to navigate the social world (Level 6). A child who is ‘just’ at Level 3 at age six is not behind a neurotypical six-year-old. They are at a different place on a developmental map that is structured by emotional and relational capacity, not chronological age. And from Level 3, the path forward is clear.
What NJ Parents Often Tell Us and What We Hear Underneath
In our work with families across New Jersey, we hear certain phrases again and again from parents who are trying to make sense of their child’s development. Here is what those phrases often really mean and how a DIR/Floortime perspective reframes them.
‘He can do it, he just won’t.’
This is one of the most common and most painful things parents say, particularly when teachers or relatives suggest that a child’s difficulties are a choice or a behavior problem. What parents are usually observing is a child who has demonstrated a skill in one context but cannot consistently access it in another. This is not defiance. It is the hallmark of a child whose skill is fragile and context-dependent not yet integrated across the nervous system. In DIR/Floortime terms, a skill that appears in one context but not others is a skill that is still being built. It needs more circles of practice, more emotional scaffolding, more contexts in which it can be safely reinforced.
‘She was fine and then she just… stopped.’
Developmental regression, losing skills a child previously had is deeply alarming for parents and is one of the situations that warrants immediate evaluation. But it is also more common than many families realize, and it does not always signal catastrophe. Children under significant stress a family move, a new sibling, a change in school, an illness sometimes temporarily regress in their developmental functioning as their nervous systems prioritize coping over growth. In children with sensory and regulatory differences, this regression can be more pronounced and more persistent. A DIR/Floortime therapist evaluates regression carefully, looking at what was lost, when, and in what context because the pattern of the regression is as diagnostically meaningful as the regression itself.
‘The school says he needs an IEP but I don’t think anything is really wrong.’
This tension between a school system’s developmental concern and a parent’s sense that their child is fundamentally okay is something we navigate regularly with New Jersey families. Both perspectives can be simultaneously true. A child can have a genuine developmental difference that benefits from support and still be fundamentally, deeply okay not broken, not less than, not destined for a limited life. An IEP is a tool, not a verdict. And a developmental evaluation including a DIR/Floortime assessment can give families a much more nuanced and complete picture of their child than a school screening alone.
Frequently Asked Questions
My child’s daycare says they are behind, but they seem perfectly happy and engaged at home. Who should I believe?
Both observations are probably accurate and together, they are very informative. A child who is regulated, engaged, and happy at home but struggles significantly in a group daycare environment is telling you something important about their sensory and social processing. The daycare environment its noise level, its unpredictability, its sensory complexity, its social demands may be exceeding what their nervous system can comfortably manage. This is not a home problem or a daycare problem. It is a child whose regulatory capacity needs building which is exactly what DIR/Floortime addresses. Bring both sets of observations to a developmental evaluation and let the full picture guide next steps.
How does a DIR/Floortime therapist assess whether a child is ‘behind’ or ‘developing differently’?
A DIR assessment goes well beyond a standardized developmental checklist. It involves structured observation of the child in play with a parent, with the therapist, and independently to map the child’s profile across all six Functional Emotional Developmental Levels. The therapist looks at sensory processing patterns (how the child responds to touch, sound, movement, and visual input), motor planning and sequencing abilities, language functioning (not just vocabulary but communicative intent), and the quality and range of the child’s emotional engagement. This profile reveals not just where the child is, but why and that why is what makes an effective support plan possible.
Is it harmful to tell a child they are ‘different’ rather than ‘behind’?
Research in developmental psychology and neurodiversity strongly suggests the opposite that framing a child’s differences as a variant of human development rather than a deficit produces better long-term outcomes for self-esteem, identity, and willingness to engage with support. Children who grow up understanding that their brain works differently not wrongly tend to develop stronger self-advocacy skills, greater resilience, and more authentic relationships than children who internalize a narrative of being broken or behind. The language we use about children’s development shapes their understanding of themselves for decades.
Your Child Is Not a Race to Be Won
Development is not a competition. The finish line is not neurotypicality. The goal is not to produce a child who looks, sounds, and behaves like every other child their age. The goal is to help your child build the internal capacities for regulation, connection, communication, and thinking that will allow them to live fully and meaningfully in the world as the person they actually are.
Whether your child is ‘behind’ in a traditional sense or developing along a genuinely different path, they deserve support that starts with understanding their sensory profile, their emotional regulatory patterns, their unique developmental map. That is what DIR/Floortime provides.
At Direct Floortime, we work with families across New Jersey in Union County, Morris County, Ocean County, Burlington County, and beyond — helping parents see their children clearly, understand what they need, and build the kind of connected, joyful relationship that makes development possible.
