On June 4, Meghan Markle and Prince Harry welcomed their daughter Lilibet “Lili” Diana Mountbatten-Windsor into the world, and the couple has already returned to their Montecito home, where Archie has had the opportunity to bond with his baby sister.

Molly Mulshine, co-host of the US Weekly royal podcast, revealed that they had spoken with someone who works with Harry and Meghan, who said:

“They are already back home in Montecito with their baby girl.

“Archie absolutely adores his little sister and gives her lots of kisses.

“He’s held her with the help of his parents.”

The toddler is “such a kind, loving child, and there aren’t any jealousy issues” with their family’s newest addition, according to the insider. Life & Style reports that Archie “loves his little sister,” and  and “treats her like a doll.”

Meanwhile, the Duke and Duchess of Sussex are “enjoying their time off to connect” with their newborn daughter, and the pair is “going out of their way to ensure” Archie “doesn’t feel left out,” according to a source.

It comes only months after their shocking March interview with Oprah Winfrey.

Having two children under the age of three is no easy task, so it’s no wonder that Meghan’s mother, Doria Ragland, has stepped in to assist relieve some of the stress.

Harry, who is dividing “parenting duties 50-50” with Meghan, “can’t get enough of” Lili, an insider previously told In Touch.

He has no qualms about completing diaper duty and gets up in the middle of the night when Lili cries, according to the source. “Obviously having a new baby takes up a lot of energy — especially when there’s a toddler in the mix too — but Harry and Meghan are enjoying every minute of it.”

Archie has also grown up a lot and is starting to carve out a life and identity for himself, People Magazine reports.

The source revealed the following about Lilibet’s birth: “[He] is very happy to have a little sister.

“They prepared Archie by talking a lot about the baby.

“He is too little to understand though.”

Despite the long nights that come with having a child, Meghan and Harry are said to be “walking on air” with joy after their daughter Lili was delivered safely.

“Meghan and Harry are so in love,” the source continued. “Lili is absolutely beautiful. She’s the perfect mix of Harry and Meghan.

“Meghan and Harry are walking on air right now. They feel very blessed.”

Meghan and Harry said in a personal statement to everyone who sent love and well wishes, saying, “On June 4th, we were blessed with the arrival of our daughter, Lili. She is more than we could have ever imagined, and we remain grateful for the love and prayers we’ve felt from across the globe. Thank you for your continued kindness and support during this very special time for our family.”
