Did you have a baby age 42+? What was it like?

I’m very tempted to have another child but I’m 42. I had my first at 28 and my youngest is 8. I know I’m fertile because I accidentally conceived a few months ago but then miscarried. Since then I’ve been overwhelmingly broody.

So if you had a baby at 42+ how was the pregnancy and young baby days? And further on how was it (if you have got that far)?
