If your baby has been diagnosed with or you suspect what happens after an early intervention referral, here is what the evidence says.

The short answer

An early intervention referral begins a structured process to evaluate whether your child has a developmental delay or disability and would benefit from therapeutic services. The evaluation is free, and services are available in every state for children from birth to age 3 under Part C of the Individuals with Disabilities Education Act (IDEA). Being referred does not mean something is wrong; it means someone wants to make sure your child has every opportunity to reach their potential.

Key takeaways

  • An early intervention referral begins a structured process to evaluate whether your child has a developmental delay or disability and would benefit from therapeutic services. The evaluation is free, and services are available in every state for children from birth to age 3 under Part C of the Individuals with Disabilities Education Act (IDEA). Being referred does not mean something is wrong; it means someone wants to make sure your child has every opportunity to reach their potential.
  • Usually normal when: You feel anxious or emotional after receiving a referral, which is a completely understandable reaction even when the referral is routine
  • Call your doctor if: Your child is approaching their third birthday and has not yet been evaluated despite a referral, as the window for Part C services closes at age 3
  • Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”

What Parents Should Know

According to CDC, NIH, Department of Education guidelines, an early intervention referral begins a structured process to evaluate whether your child has a developmental delay or disability and would benefit from therapeutic services. The evaluation is free, and services are available in every state for children from birth to age 3 under Part C of the Individuals with Disabilities Education Act (IDEA). Being referred does not mean something is wrong; it means someone wants to make sure your child has every opportunity to reach their potential. At 0-3 months, babies can be referred to early intervention at any age, and infants who were born prematurely, had a NICU stay, or have a diagnosed condition are often referred before they leave the hospital. At this age, services typically focus on supporting feeding, parent-child bonding, and early motor development. The evaluation process is play-based and observational; no one will put your tiny baby through stressful testing. It is generally considered normal when you feel anxious or emotional after receiving a referral, which is a completely understandable reaction even when the referral is routine. However, you should contact your pediatrician promptly if your child is approaching their third birthday and has not yet been evaluated despite a referral, as the window for Part C services closes at age 3.

By Age

What to expect by age

0-3 months

Babies can be referred to early intervention at any age, and infants who were born prematurely, had a NICU stay, or have a diagnosed condition are often referred before they leave the hospital. At this age, services typically focus on supporting feeding, parent-child bonding, and early motor development. The evaluation process is play-based and observational; no one will put your tiny baby through stressful testing.

3-6 months

If your pediatrician, you, or another caregiver has concerns about how your baby is developing, a referral can be made at any time. After the referral, your state's early intervention program must complete an evaluation within 45 days. The evaluation team typically includes professionals from multiple disciplines who assess motor skills, communication, cognitive development, and social-emotional functioning. You will be an active participant in the process and your input about your baby's abilities is essential.

6-12 months

At this age, evaluations often focus on motor milestones like sitting, crawling, and reaching, as well as communication skills like babbling and responding to sounds. If your child qualifies, an Individualized Family Service Plan (IFSP) is created, which outlines specific goals and the services your child will receive. Services are delivered in your child's natural environment, which usually means a therapist comes to your home or daycare.

12-24 months

Referrals during the toddler years often relate to speech and language delays, motor delays, or behavioral concerns. The evaluation process is the same regardless of age: free, comprehensive, and family-centered. If your child is found eligible, services may include speech therapy, occupational therapy, physical therapy, developmental instruction, or a combination. Early intervention has been shown to significantly improve outcomes, especially when started before age 2.

24-36 months

Early intervention services under Part C are available until your child's third birthday. If your child is referred close to age 3, the evaluation and service process is the same but the team will also begin planning for the transition to Part B services through your local school district, if needed. This transition planning ensures there is no gap in support for your child.

What to Tell Your Pediatrician

  • Describe when you first noticed what happens after an early intervention referral and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if you have concerns about your child's development but have not yet received a referral and want to request one.
  • Mention if more than 45 days have passed since the referral and you have not been contacted for an evaluation.
  • Bring a list of any questions or observations you want to discuss at the appointment.

Related Medical Concerns

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

Adrenoleukodystrophy (ALD) in Babies

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Agenesis of the Corpus Callosum (ACC)

Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
