Motor Milestone Delays — Supporting Your Baby's Development
There's a difference between "developing at their own pace" and missing foundational movements. If something feels off — rolling, crawling, tummy time — early intervention through physical therapy can make a meaningful difference.
What Are Motor Milestone Delays?
Motor milestones are the movement skills babies typically develop in a predictable sequence — and physical therapists pay close attention to that sequence because each skill builds on the one before. Tummy time builds neck strength; neck strength enables rolling; rolling builds the core and coordination needed for crawling. When babies skip or significantly delay these steps, they sometimes develop compensatory patterns that create challenges later.
A rough milestone timeline to know:
1–2 months: Brief head lifting during tummy time
3–4 months: Consistent head control; beginning to push up
4–6 months: Rolling (tummy to back typically comes before back to tummy)
6–9 months: Sitting with support, then independently
7–10 months: Crawling (hands and knees)
9–12 months: Pulling to stand, cruising along furniture
Every baby has some variation. But when a baby is significantly outside the typical range, is consistently avoiding certain movements, has difficulty with tummy time, or shows asymmetrical movement patterns, early physical therapy intervention can help identify what's holding them back and get them moving on track.
Symptoms
Signs a motor milestone delay may need PT:
Difficulty tolerating tummy time — struggling to lift the head, collapsing, or crying intensely
During tummy time, consistently pushing to one side or unable to prop up
Not rolling by 6 months, or rolling only in one direction
Asymmetrical movement — consistently favoring one side, reaching only with one hand
Not showing interest in or attempting to crawl by 10 months
Head tilt or neck tightness contributing to movement patterns
Your gut says something's off — parents often notice movement differences before anyone else does
How We Treat It
Dr. Avonlea begins with a thorough evaluation — watching how your baby moves, assessing muscle tone, strength, flexibility, and range of motion, and taking time to understand what you're noticing at home.
Treatment in 55-minute sessions includes:
Hands-on manual therapy to address muscle tightness, restricted movement, or asymmetry
Movement facilitation — guiding your baby through the developmental sequences they're missing or avoiding
Strengthening activities and play-based exercises
Tummy time assessment and customized strategies — not generic tips, but a specific plan based on what's actually making tummy time difficult for your baby
A detailed home program with clear instructions for activities and positions to use between sessions
For tummy time difficulties specifically, Dr. Avonlea evaluates the contributing factors — neck tightness (torticollis), weakness, reflux, positional discomfort — and addresses them directly. The goal isn't just to help your baby reach a checklist of milestones, but to build the foundational strength, coordination, and movement patterns that support everything that comes next.

Frequently Asked Questions
-
Trust your instincts and don't wait past the typical window. A free discovery call is the easiest first step — Dr. Avonlea can talk through what you're seeing and help you decide if an evaluation makes sense.
-
Tummy time difficulty often has a physical cause — neck tightness, weakness, reflux, or positional discomfort. Dr. Avonlea evaluates what's contributing and builds a specific plan. It usually looks very different from the standard "just keep trying" advice.
-
It's worth evaluating. Hands-and-knees crawling builds specific foundations that matter for later development. Dr. Avonlea can assess whether your baby is compensating for something or whether their development is on a different-but-fine track.
-
In most cases, no. California allows direct access to physical therapy. If your insurance requires a referral for coverage, Dr. Avonlea can help you understand your options during a free discovery call.
