Look out for certain behaviors at home and outside that continue even after pointing them out. Does your child repeatedly not listen to parents, or argues and fights with peers and adults? Poor academic performance and reading skills, and inability to understand and retain concepts or complete classwork or homework could indicate a learning disability. If your child is unable to do certain tasks like eating or dressing up independently, there could be a developmental delay. Lack of concentration, stubbornness, frequent complaints from school, inability to make friends or other negative behavior should also be checked.
