I had my first (and only) child at 42.
It was a straightforward pregnancy too (and easy to conceive). Had a normal birth, albeit with lots of epidural.
She is now 16 years old, doing her A levels and is such a blessing.
I was very fit when pregnant, used to walk one hour a day to/from work, instead of taking the public transport 5 days a week, and quite active on the weekends too, which I am sure attributed to the easy pregnancy and the straightforward birth.
