Dee I have a bugbear about the word "birthed" eg so and so 'birthed' their DS/DD it's like nails down a chalkboard to me, but that's just me. What is so wrong with giving birth, I think that sounds much better.
In your case I think you're a freaking labour hero - 50 hours in a bushfire, I'm sorry I don't care that it ended in CS you've battled through a hell of a lot more labour than I did! Hope you can feel proud of yourself for that sometime soon. Next time someone asks just tell them you were in labour for 50 hours and leave it at that!
