Martin (age 5) on the right was diagnosed with PDD-NOS two years ago. His more prominent symptoms were very significant language development delay and also significant social delay. In short, at 3yo he talked like an 18 month old, comprehended less. He threw lots of fits, many related to his difficulty understanding what was going on. He continues to have significant behaviour and speech issues but has made amazing (to us) progress. In this picture he is playing with his 18month old typically developing sister.
