["When I was pregnant with my second child, I had a really difficult pregnancy. My midwife wasn't sure either of us would make it.", 'Oh no!  It seems as though everything turned our OK, right?  I am sure you were strong!', 'Yes, in the end we both survived. He was a beautiful healthy boy and was born on a beautiful sunny afternoon.']
That is great!  It was all worth it in the end.
Once I had a difficult pregnancy. After the baby was born and both he and I were healthy and safe, I was so grateful.
