Tell me what you're worried about
Pick the one that's on your mind. I'll show you what I'd look at first as a pediatric PT, and one thing you can try today.
Not crawling yet
Or crawling looks different, scoots, or one leg drags.

Pulling up, cruising, toe walking or W-sitting.
See what I'd look at → 💬Not talking yet
Counting words, or wondering what comes before talking.
See what I'd look at → 🥄Picky eating or gagging
Only eats five foods, gags on textures, mealtime battles.
See what I'd look at → ↪️Always turns one way
Head tilt, a flat spot, or one side that does less.
See what I'd look at → 🌧️Meltdowns & big feelings
Sensory overload, tantrums and everyday activities that feel hard.

Choose what's worrying you, answer a few quick observational questions, and see what I'd actually look at as a pediatric PT: something you can try today, what to watch for next, and why the next step depends on what your child does.
Educational only. Not a screening, diagnosis or substitute for medical care.

A milestone tells you what. I help you understand why.
Milestone apps, other parents' posts and a quick "let's keep an eye on that" all measure your child against one narrow path. But development unfolds across connected areas, and no child moves evenly through all of them. Temperament, opportunity, genetics and individual variation all play a part.
Instead of…
- Checking milestone apps to see if your child is "late"
- Googling every behavior that seems off at 10 p.m.
- Comparing your child to others at playgroup
- Feeling anxious before pediatric appointments
You'll have…
- A way to see development that doesn't depend on dates
- Language to describe what you're noticing, without panic
- Clarity on what matters vs. what's just variation
- A plan to work on what's hard, and know when to ask for help
"You stop seeing delays everywhere. You start seeing your child, and you know how to help."

Filter by your child's age, from birth to 36 months, and tap the exact skill you're working on. Everyday materials, no special equipment, and step-by-step progressions so you always know what comes next.

Hi, I'm Lisa Lazor, PT.
I'm a pediatric physical therapist and an early intervention specialist in birth-to-three development. For more than 20 years my work has focused almost entirely on infants and toddlers, and I've completed thousands of developmental evaluations.
If those years have taught me one thing, it's this: children rarely develop as neatly as a milestone chart makes it look. I created Birth to Three Growth to help parents look beyond individual milestones, understand the whole child, and know exactly what to do next.
Frequently asked questions
Who is Birth to Three Growth for?
Parents and caregivers of babies and toddlers from birth to 36 months who want to understand their child's development and know what to do next, whether you have a specific worry or just want to be sure your child is on track.
What's the difference between Developmental Clarity and the Sleep Program?
The Sleep Program ($27) covers sleep only. Developmental Clarity ($97) covers all six areas of development, includes the complete Sleep Program as a bonus, 265 activities, and three months of Insiders membership.
Is the Navigator really free?
Yes. It takes about two minutes and no email is required. You'll see what I'd look at for your concern and one place to begin.
Is this a replacement for my pediatrician or therapy?
No. Everything here is educational. It helps you understand what you're seeing and supports the care your child already receives. If your child has lost a skill, had a sudden change, or you have a medical or safety concern, contact your child's healthcare provider.
What if it isn't right for us?
Developmental Clarity comes with a 30-day money-back guarantee.

EXPERT CARE
Meet Lisa Lazor PT
With over two decades of dedicated clinical experience in pediatric physical therapy, I specialize in the critical early stages of motor development. My clinical practice is built on a profound understanding of neurodevelopment, ensuring that every assessment and intervention is firmly rooted in evidence-based care and professional rigor. My academic foundation began with an undergraduate degree in physics before receiving my degree in physical therapy. I went on to complete a Master's degree in Orthopedics and obtained a Certification in Manual Therapy. I went on to further my education for a Doctoral of Science in Orthopedic Physical Therapy and am currently completing research in "congenital torticollis and its effects on delayed gross motor skills." This combination of rigorous scientific training and specialized clinical education shapes the precision and depth I bring to every evaluation and treatment plan
But beyond the science, my absolute passion lies in empowering families. I believe that early intervention is not just about meeting clinical milestones: it is about giving parents the clarity, confidence, and practical tools needed to nurture their child's unique growth journey in a warm and supportive environment.
