Meghan Markle and Prince Harry introduced their son Archie Harrison Mountbatten-Windsor on Wednesday. On the same day, Queen Elizabeth also met the Duke and Duchess of Sussex's firstborn and she was captured in a "very rare" moment during the royal baby picture.

Markle and Prince Harry shared a black and white family photo on Wednesday via the SussexRoyal's Instagram account. In the picture, the Duchess can be seen smiling while she's looking at her son and holding him in her arms. Both of them were surrounded by Markle's mother Doria Ragland, Prince Harry, Prince Philip, as well as Queen Elizabeth.

As seen in the photo, Her Majesty is smiling genuinely while looking at the latest addition to the royal family. Now, former Vogue editor Alexandra Shulman discussed Queen Elizabeth's reaction on that picture, saying she thought it was "absolutely lovely."

She told BBC Radio 4's Today there's a joyful reaction in Her Majesty's face and that is a "very rare" moment. Shulman also commented about Ragland's reaction; she is looking at her grandson and that they are the "particular stars" in the picture.

Also, she said the photocall images were very thought about - whether they're put on newspaper or shared on Instagram. Shulman explained all details in the picture were considered, and they probably had a lot of shots before picking a particular one.

She said they've chosen "very deliberately" a shot that wouldn't look like they were just there and standing there in a formal line-up to present the new royal family member. As of this writing, the image already had more than two million likes on Instagram.

On Monday, May 6, Prince Harry announced the arrival of Baby Sussex, who's seventh in line to the throne. In another related report, body language expert Patti Woods said Markle looks "physically uncomfortable" when they introduced baby Archie on Wednesday.

She said the Duchess looks different compared to her sister-in-law Kate Middleton when she introduced her three children after giving birth. Woods commented the former Suits actress seemed to be "uncomfortable with motherhood." She pointed out that Markle's faces showed signs of strain, and her steps were very small, and it's obvious there's tension around her feet and ankle.

Also, Kait Borsay encouraged new mothers to be honest about their pregnancy. The TalkRADIO host also warned Markle regarding the "rude wake-up call," noting that baby Archie sleeps soundly right now, but that would eventually change when he grows up.
