The most recent statistics show that 1 in 68 children are now being diagnosed with autism. While diagnosis is on the rise, a child typically is not diagnosed by a professional until he or she is over two years old.
However, there are signs that could indicate your child is on the spectrum as early as six months of age. Signs and symptoms can vary, as can the severity of the symptoms. Be sure to monitor your child’s development, and consult your doctor if anything concerns you. It’s important to note that autism in infants can be recognized by a lack of normal behavior, rather than the presence of strange behaviors.

Does your child smile back at you when you give her a warm, joyful smile? Does your child smile on her own? By the age of six months, your infant should be giving you big smiles or happy expressions.
