If your baby has been diagnosed with or you suspect what developmental evaluations look like, here is what the evidence says.
The short answer
A developmental evaluation is a thorough, play-based assessment that looks at how your child communicates, moves, thinks, and interacts. It is not a pass-or-fail test - it is a way to understand your child's unique strengths and areas where they may benefit from support. The process is gentle, child-led, and designed to help, not to label.
Key takeaways
- A developmental evaluation is a thorough, play-based assessment that looks at how your child communicates, moves, thinks, and interacts. It is not a pass-or-fail test - it is a way to understand your child's unique strengths and areas where they may benefit from support. The process is gentle, child-led, and designed to help, not to label.
- Usually normal when: Feeling anxious or nervous before your child's evaluation - this is a completely normal response for any caring parent
- Call your doctor if: Your child has lost previously acquired skills such as words, motor abilities, or social engagement - request an urgent evaluation rather than waiting for a scheduled one
- 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.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to CDC, AAP, Zero to Three guidelines, a developmental evaluation is a thorough, play-based assessment that looks at how your child communicates, moves, thinks, and interacts. It is not a pass-or-fail test - it is a way to understand your child's unique strengths and areas where they may benefit from support. The process is gentle, child-led, and designed to help, not to label. At 0-3 months, evaluations at this age focus on reflexes, muscle tone, visual tracking, and early responses to sound and touch. The evaluator will observe how your baby moves, how they respond to your voice, and how they react to being held in different positions. These assessments are typically brief and non-invasive. It is generally considered normal when feeling anxious or nervous before your child's evaluation - this is a completely normal response for any caring parent. However, you should contact your pediatrician promptly if your child has lost previously acquired skills such as words, motor abilities, or social engagement - request an urgent evaluation rather than waiting for a scheduled one.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Evaluations at this age focus on reflexes, muscle tone, visual tracking, and early responses to sound and touch. The evaluator will observe how your baby moves, how they respond to your voice, and how they react to being held in different positions. These assessments are typically brief and non-invasive.
3-6 months
At this stage, evaluators look at head control, early reaching and grasping, social smiling, cooing, and how your baby engages with people and objects. They may gently position your baby in different ways to assess muscle tone and symmetry. You will likely be asked questions about your baby's daily routines, feeding, and sleep.
6-12 months
Evaluations become more interactive as your baby has more skills to demonstrate. Evaluators observe sitting, crawling, babbling, response to their name, and early problem-solving like reaching for hidden toys. They often use standardized tools like the Bayley Scales or the ASQ (Ages and Stages Questionnaire) alongside clinical observation.
12-24 months
This is a common age for first evaluations. The assessment typically looks at walking, first words, pointing, pretend play, and how your child interacts with you and the evaluator. The session is usually play-based - the evaluator engages your child with toys, books, and activities while carefully observing specific skills. You will be asked detailed questions about your child's daily life and developmental history.
24-36 months
Evaluations at this age assess language comprehension and expression, fine and gross motor skills, problem-solving, social interaction, and self-help skills like feeding and dressing. The evaluation may involve multiple professionals - such as a speech therapist, occupational therapist, and psychologist - over one or more sessions. The team will share their findings with you and discuss recommendations.
What to Tell Your Pediatrician
- Describe when you first noticed what developmental evaluations look like 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 specific concerns or observations you want the team to know about - write them down and bring them to the appointment.
- Mention if your child has had a recent illness, poor sleep, or major disruption that might affect their performance during the evaluation.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Feeling anxious or nervous before your child's evaluation - this is a completely normal response for any caring parent
- Your child does not perform their best during the evaluation - evaluators are trained to account for unfamiliar settings and off days
- The evaluation takes longer than expected - thoroughness is a good sign that the team is being careful
- The evaluator asks many detailed questions about your pregnancy, birth, and family history - this context helps them understand the full picture
- You have specific concerns or observations you want the team to know about - write them down and bring them to the appointment
- Your child has had a recent illness, poor sleep, or major disruption that might affect their performance during the evaluation
- You disagree with the evaluation findings - you have the right to request a re-evaluation or seek a second opinion
- You need help understanding the results or what the recommended next steps mean for your child
- Your child has lost previously acquired skills such as words, motor abilities, or social engagement - request an urgent evaluation rather than waiting for a scheduled one
- You have been waiting an excessively long time for an evaluation and your child's development appears to be falling further behind - contact your state's early intervention program to self-refer, as you do not need a doctor's order
What You Can Do at Home
- Keep track of when you notice what developmental evaluations look like — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that feeling anxious or nervous before your child's evaluation - this is a completely normal response for any caring parent — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if your child has lost previously acquired skills such as words, motor abilities, or social engagement - request an urgent evaluation rather than waiting for a scheduled one.

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.
