Autism Warning Signs

Parenting

Here, a list of possible warning signs for autism that your doctor may use to determine if your child's development warrants further testing. Remember: Don't panic if your infant exhibits a symptom or two on occasion, but do alert your pediatrician if you notice any of the following:

By 2 to 3 months, your baby isn't making frequent eye contact.
By 3 months, he isn't smiling at you and the sound of your voice.
By 6 months, he doesn't laugh or make other joyful expressions.
Around 8 months, he isn't following your gaze when you look away from him towards something else.
By 9 months, he hasn't begun to babble.
By 1 year, he isn't consistently turning to you when you call his name
By 1 year, he shows a general disregard for vocalizations (ie, lack of response to his name), but has a keen awareness of environmental sounds.
By 1 year, he isn't engaging in back-and-forth vocalizations with you.
By 1 year, he hasn't begun to wave bye-bye.
By 1 year, he isn't "following a point" (looking towards something you point at).
By 16 months, he has no words.
By 18 months, he isn't pointing to things that interest him.
By 24 months, he has no two-word meaningful phrases.
At any time, he shows a loss of any of his previously mastered skills.
