Dear Cecil, My wife and I are expecting our second child at the end of October 2003. Our three and half year old son (born April 22,2000) was recently diagnosed with Autism. Strangely, our son received a hand-me-down chair, when he was about eighteen months old, from my mother in law's neighbour whose son is autistic. This chair still has the boy's name painted on the seat and backrest. From reading posts on this forum, we get the impression that by accepting and using this chair is similar to accepting and using someone's used mattress. Is that correct? Also, my son's bedroom is in the southeast sector of the house, and his bed is in the southeast corner of the room. His bed sheet and comforter are yellow. Could any or all of these things be contributing to his health problems? Our concern is whether or not to pass down our son's baby things (crib, stroller, high chair, car seat, clothing, etc.) to our second child for fear of the same fate and to help our son recover. Your advice will be greatly appreciated.
