Feb. 17 (UPI) -- Ivanka Trump's elder son was captured making faces Friday in the White House.

Joseph Kushner, the 3-year-old son of Ivanka and husband Jared Kushner, was spotted blowing raspberries in the Oval Office.


Ivanka later posted a photo on Instagram of Joseph and 5-year-old daughter Arabella peering out of the White House. The 35-year-old businesswoman also shares 10-month-old son Theodore with Kushner.

"Watching Marine One land on the South Lawn," she captioned the picture.

Joseph is the third-eldest grandchild of Ivanka's dad, president Donald Trump. The toddler and his sister were later photographed on a walk with the president before he took off for South Carolina and Florida.

Ivanka had treated Joseph to an outing at the Smithsonian National Museum of Natural History the day previous. She posted a photo of herself and her son from the museum's butterfly pavilion for her 3.1 million Instagram followers.

"Exploring the wonders of the @smithsonian National Museum of Natural History," she wrote.

Ivanka, whose fashion line was dropped this month by retailers such as Nordstrom, shared a video in January of Theodore crawling for the first time in the White House. She told People in April that Joseph and Arabella have adjusted nicely to their younger sibling.

"My daughter is very independent, plus she's incredibly confident of her place within the home," the designer told the magazine. "So for her I was not too worried about the transition."

"I was a little more worried about [Joseph], he's very much a a mama's boy ... [but] he's loved it," she said. "He loves giving Theodore his bottle, he loves snuggling with us for books, he's always trying to kiss him."
