1.5-year-old neurotypical child "Pointing to answer questions" 

In this video, you can see a 1.5-year-old neurotypical child pointing at it as a way to answer a few simple questions.
There were some incorrect answers due to her lack of knowledge, but she understood that "I have been asked and should answer" and she responded without leaving.
Knowing if your child is pointing like this video is important in determining whether your child is giving age-appropriate joint attention.
Baby pointing usually appears around 8-9 months of age. This is seen not only in neurotypical children, but also in children with autism.
Pointing develops in five stages.
The pointing seen in this video is the final stage. For neurotypical children, it can be obtained around 12 to 18 months after birth.
Even children with autism can develop routinely up to the second stage. However, many studies have shown that it is difficult to obtain the third and subsequent stages.
So if you are worried about your child's development, please check your child's pointing.
