Given your son’s age, I would not be surprised if the recommendation is to wait, however, I always advise parents that if the recommendation is to wait, and you notice any decrease
in your child’s
development, you contact the pediatrician at that time and not wait.
In the meantime you may wish to take a look at the websites below. They have information about early identification of children with ASD and general child development.
