KAROLINE Leavitt has given fans an adorable peek at life on maternity leave and how her young son Niko is adjusting to life as a big brother.

The White House Press Secretary shared a sweet snap of her toddler planting a kiss on his newborn sister Viviana’s head after the baby’s birth on May 1.

Leavitt posted the pH๏τo to her Instagram Story, captioning it with: “Kisses for baby sister!”

In the image, Niko — dressed in blue pajamas printed with toy cars — leans over a fluffy gray blanket to nuzzle his tiny sister, who is swaddled in a pink onesie with a matching car pattern.

Viviana’s face is covered with a white heart for privacy, but the moment speaks for itself — big brother is already smitten.

Leavitt announced the birth of her second child, nicknamed “Vivi,” via social media on May 7.

“She is here, and she is perfect,” Leavitt captioned a pH๏τo on Instagram as she was seen coddling Vivi in her nursery, noting that her family’s “hearts instantly exploded with love.”

“She is perfect and healthy, and her big brother is joyfully adjusting to life with his new baby sister,” Leavitt added.

“We are enjoying every moment in our blissful newborn bubble.

“Thank you to everyone who reached out with prayers during my pregnancy – I truly felt them throughout the entire experience. God is Good.”

At 28, Leavitt is the youngest press secretary in White House history, and the first to become pregnant while in office.

She stepped away from the podium on April 27, just days before Vivi made her entrance into the world.

Leavitt first announced she was pregnant in December while thanking President Donald Trump for his support.

The spokeswoman called the news “the greatest Christmas gift” she and her husband, Nicholas Riccio, 60, could have asked for.

She broke the news in an Instagram post showing off her baby bump in front of a Christmas tree.

In the caption, Leavitt also revealed the Sєx of her second child, writing, “The greatest Christmas gift we could ever ask for – a baby girl coming in May 2026.

“My husband and I are thrilled to grow our family and can’t wait to watch our son become a big brother.

“My heart is overflowing with graтιтude to God for the blessing of motherhood, which I truly believe is the closest thing to Heaven on Earth.

“I am also extremely grateful to President Trump and our Chief of Staff Susie Wiles for their support, and for fostering a pro-family environment in the White House.

“2026 is going to be a great year and I am so excited to be a girl mom!”

Leavitt included more pictures of her husband kissing their son Niko, who they welcomed on July 10, 2024, on the cheek.

In another picture, little Niko smiled as he hugged a teddy bear wearing a shirt that said, “I’m the big brother.”
