Lighthouse Autism Center offers resources to help caregivers recognize the early signs of autism. Here, we delve into some of the most common signs and symptoms in young kids.
Know the Signs of Autism in Babies
When do children show signs of autism? It can be difficult to recognize the early signs of autism in babies, and although autistic children often show signs in infancy, they may not be diagnosed until much later. Early signs of autism in infants or toddlers often go unrecognized simply because parents or caregivers may not know what to look for.
Recognizing the initial signs of autism can lead to an earlier diagnosis, which opens the doors for early autism intervention. Research suggests that early intervention leads to the best outcomes for autistic children and gives them the tools to lead a more independent
Missed Developmental Milestones
Developmental Milestones matter! These milestone markers offer important insight into your child’s development. Detecting missed milestones can be a crucial indicator that leads to an autism spectrum disorder diagnosis in your child. Skills such as smiling for the first time, waving, and verbal communication are just three developmental milestones.

Characteristics of Autism Spectrum Disorder
The core signs of autism in toddlers and older children are social communication challenges and repetitive or restrictive behaviors. While young children may display these characteristics on occasion, a child with autism will consistently display these characteristics, and they may interfere with their daily life. Healthcare professionals diagnose autism by assessing behaviors associated with social communication challenges and repetitive or restrictive behaviors.

Diagnostic Testing for Autism
Having a child tested for autism spectrum disorder (ASD) is only something that a qualified professional will be able to do. However, knowing the signs of autism can help you decide whether or not to seek further evaluation for your child. The easiest way to be able to determine if a child should have further evaluation for autism spectrum disorder is to know the signs. Getting an early diagnosis of ASD is key to proper treatment and early intervention.
