Ivanka Trump's children steal the show at their grandpa Donald's inauguration

It may have been Donald Trump's big day, but his grandchildren have stolen the show.

The 78-year-old took the Oath of Office Washington, D.C., on Monday, promising to bring in a 'Golden Age' in the United States as he was sworn in as president for the second time.

However, his grandchildren, Joseph, 10, and Theodore, eight, were crowd favorites, after being snapped dozing off at a church service at St. John's Church before the swearing in ceremony.

Ivanka, 43, was sitting in between her sons - whom she shares with husband Jared Kushner, 44 - but the two boys struggled to keep their eyes open during the service.

In one snap, Ivanka's eldest son was leaning against her, appearing to be fast sleep, while his brother was also on the brink of slumber.

In another snap, the boys looked cheekily up at their mom, who then proudly glanced toward her father.  

President Trump sat nearby with his wife, Melania Trump, and their 18-year-old son Barron. 

On Sunday, Eric and Lara Trump's young children, Luke, seven, and Carolina, five, became instant crowd favorites after reciting the pledge of allegiance onstage, while their parents held them near the podium. 

The adorable duo were seen walking into the church service this morning with their parents.

Carolina wore ruby slippers, white frilled socks and a navy button-up coat, as she clutched a blue fan and headed into the church with her dad.

Luke wore navy blue slacks and Nike sneakers, carrying a stuffed toy.

President Trump has 10 grandchildren in total, and will soon be welcoming another, with daughter Tiffany Trump announcing her pregnancy last year.

Ivanka looked chic in a deep-forest-green ensemble earlier today, as her father prepared for his second presidential term. 

Despite her role in her father's administration last time he was in office, Ivanka won't be resuming the same responsibilities, stating she wants to be his emotional support this time around.

Instead, she hopes to just be her father's emotional support person during this presidential cycle.

'I hate politics,' she told The Skinny Confidential podcast last week. 'I went through years of craziness.'

'It's the world's loneliest position, the enormity of the decisions you're making on a daily basis, how transactional everyone is with you,' she added.

However, Ivanka speaks to her father nearly every day and is likely to be an influence behind-the-scenes even without a formal title.

'I'm most looking forward to just being able to show up for him as a daughter and be there for him, to take his mind off things and like watch a movie with him or watch a sports game, to know that he can be with me and be himself, and just relax.'

Ivanka was not involved in her father's 2024 presidential campaign, which was a stark contrast to the 2020 race where she was a regular presence at his rallies.

The dedicated mom said said the main reason she's not returning to 1600 Pennsylvania Avenue is her children.

'The main reason I am not going back to serve now is, I know the cost. And it's a price that I'm not willing to make my kids bear,' she said.

'My primary goals were just to like, be the best freaking mom,' she said.

'Every time I had to miss something, I'm like, I will never let this happen again in the minute I leave the White House.'
