I like that final sentiment. Personally I've seen tons of people with their little toddlers and even infants in various compartments on bicycles, I see no reason why the womb is any more or less safe than most of those various compartments.

It doesn't mean there's no risk, but heck when you think about kids being strapped to parents backs/fronts/in bicycle trailers, it makes me wonder if there really is any meaningful difference in risk?

And all this doesn't even take into consideration the risks to a fetus while traveling by car.
