Was lead exposure ruled the cause of the early delivery? I'm all for eliminating environmental pollutants, but let's encourage it using things less trivial to dismiss. Edit: rereading this, it sounds harsh. I can't, offhand, think of a good way to soften it, so I'll say this: I appreciate you sharing your story and empathize with the difficulty of the lives of the people involved. I want more people to understand and internalize the need to reduce needless pollutants (safe or not, because the trend seems to usually be we think it's safe and then we find out it's not). People who don't already care or want to dismiss this issue will ignore anecdotes. If a doctor said that lead was the cause, it ceases to be what I'd consider an anecdote and it's harder to ignore.
