It may be more reasonable if you worked in a birth center. Midwives have to know a little bit of every other job in a birth center.

The only problem I can see is that labor can come at any time, so how do you tell your ultrasound supervisor that you have to leave your scheduled hours because a baby is coming? Or tell the expectant mother that she'll have to hold off on her labor, because you have to go do ultrasounds.

It'd be hard i'd think..but you can try?
