Thank you for your reply! Zhu Highest Peak: Your baby does not rule out the possibility of ADHD, but the diagnosis of ADHD is generally not given to children under 6 years old. Inattention, hyperactivity, incompatibility, and social difficulties can also be seen in other psychological disorders such as autism spectrum disorders and mental retardation, which must be ruled out before ADHD can be diagnosed. Please visit your local psychiatric or behavioral developmental specialist for further evaluation.
