I'm a white guy working in science and tech, and I only avoided jail by sheer luck (believe it or not, one day my 4-month-old baby vomited at the nanny’s, and if it had happened a few hours earlier I would have been the one arrested by the police).

I know several HNers who went through the same situation. By my calculations, the risk is about 1 in 3,000 among young parents.

tl;dr: I'll NEVER be alone with a baby under 12 months. Everyone I know who learns about this issue ends up thinking the same.
