My son's pediatrician said that one issue with babies sleeping on their stomachs is that they end up re-inhaling their own CO2 because their breathing is so shallow. I wonder if the fan is just moving the air enough to get that CO2 out of the way?

I think that's a lot of it, from what I understand, most of our sensation of suffocation is a buildup of CO2, not a lack of oxygen, so it would make sense that that's what makes people feel short of breath.

There's been some studies about fans/ moving air in babies rooms helping prevent sids, so possibly.
