About 1 in 6 children experiences developmental delays—and most catch up with the right support. This guide covers what developmental delays are, how to recognize them, and what steps to take next. If your child also has medical complexity, you'll learn how integrated care can help.
Schedule a free consultation to discuss your child's specific needs.
What Is a Developmental Delay?
A developmental delay means your child is consistently behind in gaining skills expected for their age—not just a few weeks late with one milestone, but an ongoing pattern across time.
Every child develops at their own pace. But when your child consistently misses multiple milestones, it's worth talking to your pediatrician. The good news: early intervention helps most children with delays make significant progress.
Developmental Delay vs. Disability
Developmental delays typically improve with early intervention. Developmental disabilities—like autism or Down syndrome—are usually lifelong conditions.
Early on, it can be difficult to tell the difference. That's why starting support now matters regardless of diagnosis. The NICHD offers more detail on this distinction.
Signs of Developmental Delays by Age
Watch for your child consistently missing milestones that other children their age typically reach. The earlier you identify concerns, the sooner your child can get support.
Red Flags at Any Age
These warning signs warrant immediate discussion with your pediatrician:
- No babbling by 12 months
- No words by 16 months
- No two-word phrases by 24 months
- Loss of previously acquired skills
Milestone Quick Reference
The CDC's free Milestone Tracker app helps you monitor development and share observations with your doctor.
For children with cerebral palsy, early signs may appear in infancy.
The 5 Types of Developmental Delays
Delays fall into five areas. Your child might have delays in one area or several (called "global developmental delay").
Cognitive delays affect thinking, learning, and problem-solving—like following directions or understanding cause and effect.
Motor delays affect movement. Gross motor involves large muscles (walking, climbing). Fine motor involves small muscles (grasping, writing).
Speech and language delays affect communication—either understanding others (receptive) or expressing themselves (expressive).
Social and emotional delays affect relating to others, reading social cues, and managing feelings.
Daily living delays affect self-care skills like feeding, dressing, and toileting.
What Causes Developmental Delays?
In about 62% of cases, doctors don't identify a specific cause. What matters most isn't always finding the "why"—it's getting your child support now.
Known Risk Factors
Genetic conditions like Down syndrome or Fragile X syndrome often cause delays.
Prenatal and birth factors including premature birth, low birth weight, or oxygen deprivation. Children who spent time in the NICU may benefit from specialized follow-up care.
Environmental factors including lead exposure, chronic ear infections affecting hearing, or untreated vision problems.
Medical complexity affecting multiple body systems—which we cover in the next section.
When Developmental Delays Meet Medical Complexity
Children with complex medical needs face 3.46 times higher risk of developmental delays. A 2024 study found that 45.6% of children with medical complexity have at least one neurodevelopmental diagnosis.
If your child has ongoing health conditions affecting multiple body systems, understanding this connection helps you access the right care. Our guide on what it means to be medically complex explains your options.
Why Integrated Care Helps
When medical care and developmental support happen together—same place, coordinated team—children with medical complexity often make better progress.
Traditional healthcare treats these needs separately: one doctor for medical issues, a different location for therapy. Specialized care models like PPEC address both together.
How to Get Your Child Evaluated
Start by talking to your pediatrician and requesting a developmental screening. Screening uses standardized tools to identify if your child might benefit from further evaluation.
If screening suggests delays, you'll receive specialist referrals for comprehensive testing. You don't need to wait for a definitive diagnosis to start services—early intervention is available based on developmental concerns alone.
The Parent Center Hub offers state-by-state resources for finding evaluation services.
Treatment Options for Developmental Delays
Early intervention leads to measurable improvements—studies report developmental gains of 9.5 to 12.9 points on standardized assessments.
Early Intervention (Birth to Age 3)
Early intervention provides therapy and family support at no or low cost, typically in your home or community. Services are guaranteed under federal law (IDEA Part C).
Florida families access services through Early Steps. Texas families connect with ECI.
Therapy Types
Physical therapy builds strength, coordination, and mobility skills.
Occupational therapy addresses fine motor skills, sensory processing, and daily living activities.
Speech therapy helps with communication, language, and feeding/swallowing.
Special Education (Age 3+)
After age 3, public schools provide free services through an Individualized Education Program (IEP).
Care Options for Medically Complex Children with Delays
If your child has both developmental delays and medical complexity, you need care that addresses both.
PPEC (Prescribed Pediatric Extended Care) centers integrate medical care, therapy access, and peer socialization in one licensed medical facility.
Learn more in our complete guide to PPEC and the advantages of PPEC over traditional daycare.
How PPEC Supports Development
At PPEC centers, your child's medical needs and developmental goals get attention together.
We provide some therapy services on-site and make it easy for your child's existing therapists to conduct sessions at our centers. Children also build friendships with peers who understand medical equipment and differences—supporting social development in ways home care can't replicate.

Your Next Steps
1. Request a developmental screening from your pediatrician. Share specific observations—you know your child best.
2. Follow through with referrals if screening suggests delays. Comprehensive evaluation opens doors to services.
3. Start early intervention. Don't wait for a definitive diagnosis.
4. If your child has medical complexity, explore PPEC. Check if your child qualifies and learn about Medicaid coverage.
Our enrollment guide explains the process.
Frequently Asked Questions
What's the difference between developmental delay and autism?
Developmental delays typically improve with intervention. Autism is a lifelong condition affecting social communication. Early intervention helps children progress regardless of eventual diagnosis.
How much does PPEC cost?
PPEC is fully covered by Medicaid for eligible children at no cost. Spark helps families navigate authorization paperwork. Learn how to apply for Medicaid.
Is PPEC safe for medically fragile children?
Yes. PPEC centers are licensed medical facilities, each staffed by at least one nurse with extensive pediatric experience. Meet our caregivers and learn more about medical daycare safety.
Can PPEC help with multiple types of delays?
Yes. We offer some therapy services on-site and welcome your child's existing therapists to our centers—addressing multiple delay types in one familiar location.

Moving Forward
Developmental delays affect 1 in 6 children, and early intervention helps most children make meaningful progress.
If your child has both delays and medical complexity, integrated care addresses both needs together. At Spark Pediatrics, children receive nursing care while working with therapists and making friends—all under one roof.
