Many of the parenting books include developmental markers to look for in the rapidly changing period known as early childhood.These are helpful to provide reassurance, what to look for, and what to expect. However, it is also important to know that every child develops on their own individual timeline. This guide serves to explain what can be done if development is veering far off track from expected, and why the earlier the intervention the better in terms of your child’s growth and success.


Breaking it down

Don’t just wait and see

The term “early intervention” is a broad term referencing the services and supports available to babies and young children who are exhibiting developmental delays or have a diagnosed disability¹. Typically, this term applies to children up to age 3. Children older than age 3 who need services and support access these through the local school districts. Every state has a different program, with free or reduced cost services as needed. While this is not a complete and exhaustive list of the types of diagnoses/disabilities, this is a list of some of the most common conditions or disabilities that may qualify for early intervention services.

  • Attention deficit/hyperactivity disorder “ADHD” (rarely diagnosed before age 3)

  • Autism spectrum disorder “ASD”

  • Birth injury

  • Blindness or vision impairment

  • Cancers

  • Cardiac conditions

  • Cerebral palsy

  • Cleft lip or cleft palate

  • Cystic Fibrosis

  • Down Syndrome and other chromosomal disorders

  • Encephalophy

  • Epilepsy

  • Failure to thrive

  • Fetal alcohol syndrome

  • Hearing loss or hearing impairment

  • Low birth weight

  • Metabolic disorders

  • Muscular disorders

  • Post-traumatic stress disorder

  • Skeletal disorders

  • Skull deformity

  • Spina bifida

  • Spinal cord injury

  • Traumatic brain injury

Early interventions come in many shapes and sizes!

For children who need a bit more support due to developmental delay or diagnosis, early intervention leads to better outcomes. Depending on the child, diagnoses can occur as early as before birth, if prenatal check and scans have found a genetic condition. Diagnoses can also occur all the way throughout the lifespan, with many different factors at play. Children who receive early intervention have better academic outcomes, improved behavioral outcomes, and better social / emotional outcomes. There are economic benefits too - early intervention is associated with long term cost savings in education and therapy needs in the future²,³.

We have learned that in the postnatal period, there are “critical periods” of development that are essential for acquisition of skills like language, motor planning, sensory development, etc⁴. Your child grows and develops rapidly! You aren’t just imagining that they are outgrowing their clothes overnight - and the cognitive, language, motor, and social development of your child is happening just as fast. It can be difficult - or almost impossible - to “make up” for this time, if the window closes. The first five years of life are absolutely full of these critical periods. In fact, 80% of a child’s brain is developed by age 3, and 90% by age 5⁵.  Of course children still grow and learn and develop after 5 years of age - in fact, the brain is not fully developed until a person reaches their 20s. Yet this early period is when neurons are pruning, and connections are made. Capturing the receptivity of the brain's neurons and “neuroplasticity” or ability to change is the best predictor of future development⁶. 

It can be nerve wracking to think that something may be off with your child’s development, and there can be a myriad of reactions as a parent - as well as from well-meaning friends and family. Reassurances might be offered, and you may be encouraged to “wait and see.” Anecdotes from fellow parents about a slow-to-talk child who later exploded with language can be comforting.  You may hear from friends about a child who skipped the crawling stage, skipped the toddling stage, and went right into running. And we have made considerable progress in our acceptance of individual differences and developmental delays. Yet there is still a lot of shame and stigma with thinking that something may be “wrong,” and the part missing from that language explosion story could be the 1-2 times a week visits with the speech therapist, thanks to early intervention.

At every point and stage of your child’s life, if you have a concern, it is better to look into it - better to know that your worries were for naught, than to miss an opportunity to help your child overcome a challenge or obstacle at the most effective point in their development.

If your child is born with a disability or is diagnosed at birth with a delay, early childhood intervention services can start as early as in the hospital, with feeding therapies and physical therapy. As your baby develops, these services can transition into cognitive, speech, occupational, physical, medical and nursing services, and play therapy - anything to help the baby and toddler learn and develop the basic skills essential to the first three years of life. 

Depending on need, family supports such as family therapy, respite support, and nutritional services may also be available. Not every child will need every therapy, but there are lots of different supports, and combinations of support, available for you, your child, and your family.  Below is an overview of different support options available and what they may look like in practice.

Developmental testing is the best way to understand your child’s development in an objective manner. This type of testing is typically non-invasive and may involve activities with pencil and paper, blocks, and other interactive exercises (See Screening and Assessment guide for more). If you are on the fence about testing, know that there is little downside. Whether testing results demonstrate your child is right-on-track or needs some extra support, it’s always helpful for your child in their current life stage, and even in later childhood and young adult years, to have data demonstrating their developmental experience.. This is why pediatricians screen at well-child visits as well, but you as a parent are always going to be the best front-line observer for if there is a need for a bit more support⁷. Best practice is for pediatricians to ask about development at every single visit. Formal screenings (usually a validated checklist, may also be an interview with parents) should take place at 9 months, 18 months, and 30 months⁸.

You do not need to wait on a pediatrician or professional to refer you for services - if you are concerned, at any point, for your child’s development, you have the right to directly request an evaluation for services. If your child is below age three, you will contact your local state run program. At age 3, the local school district takes over, and you will contact them, even if your child is not enrolled in school (more on this below).

All of this is ensured for your child through the Individuals with Disabilities Education Act (IDEA), specifically Part C - the Program for Infants and Toddlers with Disabilities⁹. It specifies an urgent and substantial need to, among other things:

  • Enhance the development of infants and toddlers with disabilities, to minimize their potential for developmental delay, and to recognize the significant brain development that occurs during a child’s first 3 years of life.

  • Maximize the potential for individuals with disabilities to live independently in society.

  • Enhance the capacity of families to meet the special needs of their infants and toddlers with disabilities.

The Individuals with Disability Education Act (IDEA) is federal law that specifies that all children are entitled to a free, fair, and appropriate public education¹⁰. Children ages 3 and older are eligible for services through the local school district if they have aged out of early childhood intervention, but still need services, or if they are identified as having developmental delays after age 3.

So you want an assessment . . . where do you start?

What the research says

  • Increased early intervention services are associated with greater gains in development¹¹

  • Early intervention is associated with academic achievement, improved behavior, educational progress and degree attainment, among other benefits in adulthood¹²

  • Early intervention supports parents as well as the developing child, and fosters parent/child relationships, while decreasing anxiety¹³

  • 20-30% of late talkers will not catch up to peers without intervention - it's not worth it to “wait and see”¹⁴

  • There is an increased risk of mental health disorders in children who do not receive early intervention services¹⁵

What it might look like for you

Any intervention for your child should be individualized and tailored for their specific needs, and your specific needs as a family. However, there are a few consistent steps you can expect.

Remember, every child is different, and so the individualized plan developed for your child may look very different than it did for your neighbor, nephew, or friend.
