4. Fails to point to objects
Before a child has developed her verbal skills, she usually points to objects that she is interested in. For example, if she is hungry, she will point to a bottle, or if she wants to play with a toy, she’ll point to the toy. She may also reach toward the items she is interested in. Pointing is a basic form of communication that usually develops by 6 months of age. Should you notice that your child is not pointing to objects by the age of 1, it could be a sign of autism.
