She wrote: "Forever grateful that even though my childbirth did not go to plan, I was surrounded by compassionate, skilled, knowledgeable and experienced women from start to finish.
"Here is my deepest, most heartfelt thank you to all the midwives out there who pull long shifts, have to make difficult decisions under pressure, have seen a hell of a lot of good and bad, and exercise compassion and reassurance every single day for those under their care.

"Also to the obstetricians who are exactly where they need to be, exactly when they need to be there, and who manage to see the whole thing through with what seems to be complete ease."
She then paid a loving tribute to her former rugby star husband. "And @jameshaskell, after I nearly fired you from your post for fear you would be at another DJ gig when I went into labour, you were the DREAM birth partner.

"I couldn't have wished for anyone better to hold my hand and talk me through everything from start to finish. thank you. I love you. We DO make cute babies."
