I use it for anything red and sore, so lips, rashes, spots, cuts, grazes, etc.
I don't know whether I'd take it to hospital for the baby, but you might be able to make use of it on yourself if you happen to get any minor scrapes during labour and birth. I used mine on my drip insertion points on the backs of my hands. Not sure if that's recommended, but that's the kind of thing I use it for.
