While I can sympathize with Jenny Mccarthy, she isn't a medical expert and her views are decidedly at odds with the medical establishment, so take that into consideration when you listen to what she has to say.
however, you might check out web sites of orgs like Autism Speaks (www.autismspeaks.org) or the CDC (http://www.cdc.gov/ncbddd/actearly/index.html). Flags do vary but lack of speech, lack of response to name, inappropriate play with toys (ie obsessing with wheels on a car) are some flags. Lack of eye contact is a warning as well but making eye contact doesn't eliminate the possibility as this is something that may fade. (My son is 2 and speech-delayed so the possibility of his being autistic has been a concern. i also have a nephew who's autistic. I've learned a bit about this along the way.) If you are concerned, have him tested. Early intervention is absolutely the best thing that can happen! Good luck!
