Autism in Babies

Autism in babies is a condition that negatively impacts their interactions. Also, the baby finds it to be a hefty task to form a relationship with the world. This disorder is seen in 1 out of every 54 children. Furthermore, autistic babies show a wide range of signs and symptoms – decreasing eye contact, little to no response to being called, muted expressions on their faces, and so forth.

Thus, once you’re aware of these symptoms, watch out for them, and if you have even a small doubt that your baby may be autistic, take them to a pediatrician immediately. Other than this, the causes of autism can be varied – genetic, being born from older parents, the mother having diabetes, etc. Moreover, autism can be diagnosed and treated with proper screenings. But there are no therapies that can cure autism.

Autism spectrum disorder (ASD) is a condition where a person’s interactions, communications and behaviors are affected. And all this happens when the individual is growing up. The CDC has found that autism can be noted in 1 out of every 54 children. While it’s true that boys are more affected by this disease than girls, still, it’s common in all ethnic and socio-economic groups.

Top 4 Signs and Symptoms of Autism in Babies

Symptoms of Autism in Babies

An autistic baby will not look different. But the baby finds it different to relate to and communicate with the world that surrounds them. And because autism is a disorder with largely distinct signs and symptoms, it’s known as a “spectrum” condition. Take your baby to a health care professional if any of the mentioned signs and symptoms come to your attention.

1. Decreasing Eye-contact

At around 2 months of age, babies usually learn to find faces with their eyes and make eye contact. And eye contact paves the way for them to create good relationships and collect information from their surrounding places. Furthermore, if infants who are not good at making eye contact well at even 2 months of age, then, it may mean that they have autism.

2. Declining Pointing and Gesturing

Before your little one begins to speak, they communicate with you through gestures. If a baby is not using gestures and pointing at things or people, there may be chances of autism or even language delay. Moreover, your baby’s gaze won’t pinpoint the place where you are pointing at. And such skill is known as “joint attention”, which is reduced in babies with autism.

3. Limited or No Reply to Being Called by Their Name

When babies become at least 6 months old, they reply to their names by gestures, expressions, or voices. And researchers have seen that infants with autism typically don’t respond to their names by 9 months, and later they develop autism. Moreover, this non-responding happens in a pattern and not just one or two times.

4. Facial Expressions Show Fewer Emotions

Autistic children do feel the same level of emotions as children do. But studies on school children have discovered that a lot of their emotions don’t manifest through their facial expressions.

Diagnosis of Autism in Babies

If the baby is showing any signs or symptoms of autism, it is recommended that you take them to screenings and diagnosis. The doctor will conduct evaluation tests based on observing the baby and asking you questions regarding the baby’s responses to various stimuli and whether they are reaching their milestones.

According to the American Academy of Paediatrics (AAP), the baby should go through an assessment of their development in all their visits. Further, you should take them to development delay screenings at 9th, 18th, 24th and 30th month. It is advisable that ASD-specific screenings take place when the baby is between 18 and 24 months old.
