What Causes Developmental Delays in Children?
A Parent’s Guide by Pranaah Child Development Centre, Kollam
Under the leadership of Dr. Devi Raj, Licensed Early Interventionist
Every child grows at their own pace, but some children take longer to develop speech, movement, social skills, or learning abilities. This can be confusing, worrying, and emotionally challenging for parents. At Pranaah Child Development Centre, led by Dr. Devi Raj — a Licensed Early Interventionist, we support families every day who are asking:
“Why is my child delayed in speech?”
“Why is my child not walking or talking like other children?”
“What causes developmental delays?”
“Is there something I should have done earlier?”
This guide explains, in simple and reassuring language, the most common causes of developmental delays — and what you can do as a parent.

⭐ What Are Developmental Delays?
A developmental delay means a child is developing slower than expected in one or more areas:
Speech & Language
Movement (Gross & Fine Motor Skills)
Cognitive Skills (Thinking & Problem-Solving)
Social & Emotional Development
Self-Help Skills (Eating, Dressing, Play Without Support)
A delay doesn’t mean a child cannot learn — it simply means they need extra support, especially early in life.
⭐ Common Causes of Developmental Delays in Children
Under the guidance of Dr. Devi Raj, Pranaah follows evidence-based assessment to understand the root causes. Here are the most common reasons:
1️⃣ Genetic or Chromosomal Conditions
Some delays occur due to genetic differences such as:
Down Syndrome
Fragile X Syndrome
Other genetic abnormalities
These affect overall development, but early intervention significantly improves outcomes.
2️⃣ Premature Birth
Babies born too early often have:
Weaker muscles
Feeding difficulties
Delayed speech
Increased risk for developmental challenges
Many premature babies catch up with proper therapy.
3️⃣ Hearing or Vision Problems
A child who cannot hear or see well may:
Speak late
Struggle with social interaction
Find it hard to follow instructions
Early screening is essential.
4️⃣ Neurological Conditions
Conditions affecting the brain may contribute to delays:
Cerebral palsy
Seizure disorders
Brain injuries
Early therapy supports mobility, communication, and learning.
5️⃣ Autism Spectrum Differences
Children with autism may show delays in:
Speech
Eye contact
Social interaction
Play skills
Many parents first notice that their child “is not speaking like others.”
With early intervention, children show excellent progress.
6️⃣ Environmental Factors
The child’s surroundings also play a role:
Limited language exposure
Excessive screen time
Lack of play opportunities
Poor nutrition
Neglect or trauma
Small changes in daily routine can make a big difference.
7️⃣ Medical Conditions
Illnesses, infections, or long hospital stays may impact development.
Examples include:
Chronic ear infections
Low birthweight
Nutritional deficiencies
Untreated jaundice in newborns
8️⃣ Unknown Causes
In many cases, parents have done nothing wrong.Sometimes delays happen without any clear cause.
What matters most is early identification and the right support.
⭐ Early Signs Parents Often Notice
You should seek a developmental evaluation if your child:
Isn’t speaking words by 18 months
Has unclear speech after age 3
Doesn’t follow instructions
Avoids eye contact
Isn’t walking by 18–20 months
Struggles to hold a pencil or feed themselves
Has difficulty interacting with other children
Displays repetitive behaviours
Has sensory issues
⭐ The Importance of Early Intervention
Research proves that the earlier the support, the better the progress.

❓ FAQ: What Causes Developmental Delays in Children?
1. What is the most common cause of developmental delays?
Delays often occur due to prematurity, hearing issues, autism spectrum differences, genetic conditions, or limited language exposure.
2. Can developmental delays be corrected?
Yes. With early therapy and consistent intervention, most children show remarkable improvement.
3. Does screen time cause developmental delays?
Too much screen time can reduce language exposure and affect attention, social skills, and speech development.
4. Is developmental delay the same as autism?
No. Autism is one possible cause of delay, but many children have developmental delays without autism.
5. When should I worry about my child’s development?
If your child is consistently missing milestones — especially in speech, social skills, or motor development — it’s best to get a developmental screening.
6. Who should I consult if I suspect a delay?
A Licensed Early Interventionist, like Dr. Devi Raj at Pranaah, can evaluate your child and guide you with the right therapies.
