Ivanka Trump's father may have just become the most powerful man on earth - but it was her baby's achievements that she decided to celebrate on Wednesday.

She posted a video on Instagram showing the 10-month-old Theodore crawling on the carpeted floors of the White House just one day after she showed off his immaculate new nursery in Washington DC.

Ivanka wrote: 'There were so many incredible milestones this past weekend -- including one for baby Theodore who crawled for the very first time in the White House!'

Ivanka Trump's father may have just become the most powerful man on earth - but it was her baby's achievements that she decided to celebrate on Wednesday

She posted a video on Instagram showing the 10-month-old Theodore crawling on the carpeted floors of the White House

She wrote: 'There were so many incredible milestones this past weekend -- including one for baby Theodore who crawled for the very first time in the White House!'

The video captured Theodore crawling as Ivanka gasped in the background with excitement at her baby's developments.

Ivanka soon got on her hands and knees, wearing a black turtleneck, with skinny black trousers and pointed flats.

She paired with the sleek outfit with the same headband she wore to attend a national prayer service on Saturday.

Ivanka called her son her 'monkey', sat down on the ground next to him, and said: 'Do you want to do it? You ready? I think he's ready!'

She enlisted her daughter Arabella, and told her to encourage Theodore as she marveled at her baby and said: 'He's moving!'

Sister in law Lara also shared a photo from the grand dining room with husband Eric

The first daughter also shared a bedtime photograph of her youngest son Theodore inside his immaculate new nursery on Tuesday.

'Goodnight!' she wrote alongside the image of the beaming baby who sat upright in his crib for the snap.

A white and grey monogrammed pillow with his initials, TJK, rested behind him and two throws had been folded over the side of the crib.

The nursery was also decked out with a boat print wallpaper, a blue velvet sofa, and a charcoal grey, paper mobile.

Jared Kushner, on the other hand, was spotted rushing out of his new Washington DC home earlier in the day ahead of a busy day at the office.

The senior adviser to Trump wore an inconspicuous black suit and tie with a white button down as he made his way to a waiting SUV while speaking on his phone.

He carried with him a small notebook as he prepared himself for his day at the White House.

Ivanka made a much more low key exit as she jumped into a car with the couple's three children on Tuesday, choosing to exit from the garage so she could not be seen by waiting photographers and the public.

New gig: Tuesday marked Kushner's second day at his job working as an unpaid senior advisor to his father-in-law, President Donald Trump

On Monday, Ivanka was photographed exiting her house and getting into a waiting SUV on Monday, with her head shielded from the cameras by a giant umbrella.

She was joined by her Secret Service detail and son Joseph, who joined her for lunch at the Open City coffee shop in Woodley Park.

Ivanka, 35, and her family moved to DC over the weekend, and Kushner began his unpaid job as a senior adviser to President Trump in the White House.

Last week, Ivanka finally broke her silence about rumors that she might fill the role of first lady when her father takes office on Friday in an interview with 20/20.

'Well, I think its an inappropriate observation. There's one first lady and she'll do remarkable things,' said Ivanka, referring to her father's wife Melania.

She later told Deborah Roberts in the interview that she also found the comments 'sexist,' saying that they seemed to suggest that two women could not have a powerful role in her father's White House administration.

Ivanka also revealed during the interview that she is still close to former first daughter Chelsea Clinton despite her father's victory over Hillary in the election, and said that she will likely go to her for advice.
