Speech delay or autism? 3 y/o- says few words but no sentences. Knows letters n sounds, helps with clothes/shoes, etc. No mom, dad, hungry, eat, etc.

Speech delay=sure. Whether this is part of autism or a speech/language issue can only be determined by a full evaluation.If you are in the US, there is a program called Child Find operated in all public school districts.Their job is to take any kid 3 and over and identify their special needs and try to make the kid school ready by 6.Contact special services in the area you live and get started.
