Autism is a neurodevelopmental disorder that affects communication skills and social interactions. It is estimated that around 1 in 59 children have autism spectrum disorder (ASD) in the United States.
According to recent studies, the second child in a family is more likely to have ASD than the first child.
What is Autism Spectrum Disorder (ASD)?
ASD is a complex neurological disorder that affects how a person engages, communicates, and relates to others. Symptoms of autism can be recognized in early childhood usually around the age of 2 or 3, but in some cases, it can be picked up later.
Some of the common signs of ASD include repetitive behavior, speech delays, restricted interests, and sensory sensitivity. Children with ASD also struggle with developing and maintaining social relationships, which can make it difficult for them to communicate and express their emotions.
Why is the Second Child More Likely to Have Autism?
Although the exact causes of autism are not known, research has shown that genetics plays a significant role in the development of the disorder.
Studies have confirmed that parents who have one child with autism have a higher risk of having a second child with autism. Researchers are unsure why this is the case, but some theories suggest that second-born children may be exposed to different environmental factors, such as prenatal or perinatal complications, that increase the risk of developing autism.
Scientists have also discovered that mutations in specific genes increase a child’s risk of having autism. Some of the genes linked to autism include SHANK3, CHD8, and SYNGAP1.
These genes are crucial to healthy brain development, and any abnormalities or mutations can lead to autism. It is possible that the second child may inherit a particular gene that wasn’t present in the first child, which increases their risk of developing autism.

The Importance of Early Diagnosis and Intervention for Children with Autism
Early diagnosis and intervention are essential for children with autism. Research shows that early intervention can significantly improve the outcome for children with autism by promoting social, emotional, and intellectual growth.
Children with autism receive individualized treatment plans based on their unique symptoms, strengths, and challenges. The treatment plans may include applied behavior analysis (ABA), speech and language therapy, occupational therapy, and sensory integration therapy.
Early diagnosis also helps parents and caregivers to better understand their child’s needs and how to provide appropriate support at home and at school.
Parents of children with autism should educate themselves about the condition and seek out resources and support groups in their community.
Preventing Autism
Unfortunately, there is no way to prevent autism at this moment in time, but some studies suggest that early intervention can help reduce the severity of symptoms. Pregnant women can take steps to reduce their child’s risk of developing autism.
These include:.
- Avoiding alcohol, tobacco, and drugs during pregnancy
- Taking prenatal vitamins
- Eating a healthy and balanced diet
- Getting regular exercise
- Getting enough sleep and rest
- Managing stress and anxiety
- Scheduling regular prenatal checkups
The Bottom Line
Autism is a complex neurodevelopmental disorder that affects communication skills and social interactions. While there is no cure for autism, early intervention can help improve outcomes for children with ASD.
Studies have found that the second child in a family is more likely to have autism than the first child, but the exact reasons for this are still unknown. Parents of children with autism should educate themselves about the condition and seek out resources and support groups.
