I read an interesting blurb about a possible cause for the kid's medical condition... It's apparently related to over-exposure to cleaning chemicals, and John Travolta has admitted that he somewhat obsessively cleaned his child's carpet (and probably the rest of his childhood environment). That's gotta be a terrible thing, trying to protect your kid and finding out later that your efforts might have killed him. Whether the obsessive cleaning caused the condition or not doesn't matter, because he'll always wonder and that's a terrible thing to have to live with.
Every day I wonder if I'm doing the right things for my kid...
