Despite what parents may say about their child and their behaviors, attention- deficit-hyperactivity disorder(ADHD) is a very difficult disorder to diagnose during a child’s first year of life. Behavior that is exhibited in a three to five year old is normal for a baby. A baby’s attention span, at nine months is not very long, and the frustration level is just naturally greater in an infant or toddler, than it would be in an older child. I would have to say, that the disorder (ADHD) is difficult to detect during the first year of a child’s life.
I would encourage parents to read all the information they can about their suspicions with regard to any disorder.
