If you have 8 year old girls, I can't be sure but I'd imagine they'd love a new sibling. I am almost 40 and fell pregnant unexpectedly...she is 5 months now and my kids absolutely adore her. My eldest is 11 and she was an amazing help! My pregnancy was more tiring than the others and I did have an iron infusion towards the end but apart from that all good.
My second was born when I was 41. Planned pregnancy , conceived naturally after 2 cycles. Easy pregnancy until I developed pre eclampsia at 37 weeks and was induced. Also, natural birth. Very blessed at my age really. . But yes, the risks are higher and I was closely monitored by my OB.
My first was 3 years old when she was born so I can’t comment on the second part of your question about older kids and how they coped etc.
