Deep Dive: Crawling
It isn't just a milestone, and that's exactly why it matters.
There’s a moment in early development that doesn’t get nearly enough attention.
It’s not the first word. Not the first step. Not even the first smile.
It’s the moment a baby figures out they can move themselves across space with intention.
Crawling.
And if we’re honest, crawling has been quietly downgraded in modern parenting culture to something optional - like a bonus level in development that some kids play and others skip on their way to walking.
But from where I sit, as a pediatric occupational therapist, crawling is not optional. At all.
It’s foundational in a way that’s easy to miss until later.
The myth of “just a phase”
Crawling is often treated like a transitional stage. A box to check on a developmental chart before we move on to more “important” things like speech, potty training, or preschool readiness.
But that framing misses something essential: crawling is not a phase of movement.
It’s a phase of organization.
Because before a child can walk through a room, sit at a desk, hold a pencil, or navigate a crowded playground, their brain has to figure out something much more complex. It has to figure out how to coordinate two sides of a body that don’t naturally want to agree with each other.
What crawling is really asking the brain to do
If you slow it down - really slow it down - crawling is almost absurdly complex.
A baby has to:
Shift weight between both shoulders and hips, without collapsing
Coordinate opposite sides of the body in a rhythmic yet opposite pattern
Stabilize the core while moving limbs independently
Track where they are going while their body is doing something entirely different
Continuously adjust balance against gravity
No one teaches this in a linear way.
It emerges through repetition, trial, error, frustration, curiosity, and a lot of face plants into soft rugs.
And underneath all of that visible movement is the brain is wiring itself for coordination.
