Speaking out about her birth experience on Giovanna Fletcher's Happy Mum, Happy Baby podcast, Kate later admitted it had been "terrifying" to give birth to her first child.
With the world's press waiting outside of the Lindo Wing at St. Mary's hospital in London for any news, Giovanna asked Kate to think back to that day to express how she felt.

"It was slightly terrifying; I'm not going to lie. Everyone had been so supportive and both William and I were conscious that this was something that everyone was excited about, and we are hugely grateful for the support that the public has shown us, and actually for us to share that joy and appreciation with the public was equally important.
"But equally, it was coupled with a newborn baby and inexperienced parents and the uncertainty about what that held. So, there were all sorts of mixed emotions."
