The great Kate wait continues — but that doesn't hinder the Duchess of Cambridge from performing her everyday mothering duties for older son, Prince George. Proving that a mother's work is never done, Kate Middleton, 33 — now five days passed her April 23 due date — was spotted Tuesday, April 28 picking up her 21-month-old from swimming lessons at Buckingham Palace, Us Weekly has learned.

An onlooker tells Us the royal — who drove herself! — was joined by a protection officer who rode shotgun during the 11 a.m. trip to pick up George from lessons. Prince George's nanny, Maria Borrallo, was also along for the ride back to Kensington Palace.

News of Middleton's surprise outing comes just hours after she and her husband Prince William, 32, sent a breakfast treat to royal watchers patiently waiting outside the Lindo Wing of St. Mary's Hospital in London. Around 9 a.m. local time, the second-time parents-to-be sent tea and two boxes of Danish pastries and croissants — in boxes wrapped with pink ribbons! — to the camped-out Brits.

A palace aide tells Us, "The Duke and Duchess saw reports of them camped out and wanted them to know they were thinking of them."

As the world awaits (and awaits!) the arrival of royal baby no. 2, there’s a group of royalist super fans camped outside of the Lindo Wing of St. Mary’s Hospital in London, ready for the moment the pregnant Duchess of Cambridge goes into labor. These excited Brits are decked out, head-to-toe in Union Jack prints and wear shirts with Prince George’s face on them that read, “I Was Here First.”

So around 9 a.m. on Tuesday, April 28, the royal couple sent 10 cups of tea and two boxes of Danish pastries and croissants. The royalists immediately noticed that the boxes were tied with pink ribbons, wondering if that was a hint at the baby’s gender.

One of the camped-out Brits, John Loughrey, tells Us Weekly, "We couldn't believe it. One of the officers dropped it off and said it was from the Duke and Duchess of Cambridge. It was a lovely gesture, smashing."

Now five days past her April 23 due date, Kate Middleton is patiently waiting with her husband Prince William and their son Prince George at Kensington Palace. Unfortunately, Prince Harry will not be present for the baby’s birth as he returned to Australia yesterday to continue military training.
