All natural; no pain-relief; looking like a superstar mere hours later – we have to say that Kate Middleton gives us all sorts of #BirthingGoals.

Although the British royal rarely talks of the birth of Prince George and Princess Charlotte (we'd murder a bit of Kim Kardashian-inspired pregnancy overshare, tbh), she has now opened up about her experiences at St Mary's Hospital.

And it seems that she was cared for "brilliantly" during her time there in July 2013 (for the birth of Georgy Porgy) and May 2015 (for little Lottie's arrival).

The Duchess, natch, gave birth on both occasions in the fancy-pants, oh-so private Lindo Wing (think art installations, chef-made food, afternoon tea and champagne). But St Mary's itself has many public amenities too – including a children's intensive care unit that is now in desperate need of an upgrade.

Step forward the wholly-worthwhile More Smiles Appeal – which aims to raise €2.85m so it can redevelop the unit that currently cares for 400 critically ill children from London and its surrounding area.

Backing the appeal is the always-lovely Kate, who said in a statement: "The thought of your child in an intensive care unit is harrowing for any parent.

"The commitment to expand and transform the children's Intensive Care Unit at St Mary's Hospital will vitally guarantee more space to treat more children and support more families. 

“As someone who was so brilliantly cared for by St Mary's, I am delighted to support [the appeal], and commend the important work of all those involved in the project." 

The scheme is all part of a larger drive to raise some €14.25m for improvements which will allow more than 200 extra children to be cared for each year.
