When should I be concerned?
One of the most important things you can do as a parent or caregiver is to learn the early signs of a developmental disability and become familiar with these milestones.
"Red Flags"
Here is a list of some “red flags” that may suggest a risk for a developmental delay or possible neurodevelopmental disorder such as autism:
- No big smiles or other warm, joyful expressions by six months or thereafter
- No back-and-forth sharing of sounds, smiles or other facial expressions by nine months
- No babbling by 12 months
- No back-and-forth gestures such as pointing, showing, reaching or waving by 12 months
- No words by 16 months
- No meaningful two-word phrases (not including imitating or repeating) by 24 months
- Any loss of speech, babbling or social skills at any age
- No response to name by 12 months
If your child is showing any of these or is not meeting any of the milestones by the age listed, don’t panic. Reach out to your pediatrician or family health care provider and let him or her know about your concern. To prepare for talking with your child’s health care provider, note what milestones your child has or has not yet reached compared to other children his or her age. Before or during the visit, ask for a general developmental screening. If you are worried that it could be autism, you can also fill out an autism screener (one is provided at the end of this tool kit) and bring the results to your health care provider visit.
