Duchess of Sussex

"I knew, as I clutched my firstborn child, that I was losing my second," Meghan said in a piece for the New York Times.

She went on to describe how she watched "my husband's heart break as he tried to hold the shattered pieces of mine".

Meghan wrote that "loss and pain have plagued every one of us in 2020".

The 39-year-old shared her experience to urge people to "commit to asking others, 'are you OK?'" over the Thanksgiving holiday in the US.

The SussexRoyal Instagram account shared an image of Meghan, who is American, holding her son's heel.

In the caption, the account paid tribute to "all mothers today, past, present, mothers-to-be, and those lost but forever remembered".

While Mother's Day is in March in the UK, it was marked in the US on Sunday.

It was also celebrated in Canada, New Zealand, Australia, South Africa, Kenya and Japan.

The photo was accompanied by the poem Lands, by writer Nayyirah Waheed.

Archie Harrison Mountbatten-Windsor was born weighing 7lb 3oz on Monday.

A beaming Prince Harry said they were "absolutely thrilled" and thanked the public for their support.

He said Meghan and the baby were doing "incredibly well", adding that they were still thinking about names for the infant, who was delivered at 05:26 BST.

Buckingham Palace said the baby weighed 7lbs 3oz (3.2kg), and that the duke was present for the birth.

The baby boy is seventh in line to the throne, behind the Prince of Wales, the Duke of Cambridge and his children - Prince George, Princess Charlotte and Prince Louis - and Prince Harry.

The Duchess of Sussex, cradling her baby bump as she is wont to do, visited one of her four new patronages, an animal welfare organisation called Mayhew earlier this week.

While being introduced to a group of volunteers and beneficiaries, Meghan met a woman whose name is Peggy McEachrom, according to People magazine.

In an adorably awkward moment captured on video, McEachrom paid the former Suitsstar several compliments, including one particularly unexpected one.
