Are ASD symptoms present in infants and toddlers?
• 30-54% of parents register their first concern <12 months, in children diagnosed with autism
• 80-90% of parents recognize child abnormalities < 24 months.
YES!

Joint Attention Skills* TYPICAL ASD
8-10 months Gaze monitoring No eye contact
10-12 months Following a point Does not respond to request “oh look!”
12-14 months PIP Develops advanced self help skills
14-16 months PDP * Consistently absent
14-18 months Show and tell Often brings to parent to obtain repeated action
*Joint attention deficits appear to be specific to ASD and reliably differentiate children with ASD from other developmental disabilities.

PDP: Pointing merely to show!
