The little boy looks right at home in his big boy seat as he sits up with his arm casually hanging off the side of the chair. 

The image has been liked more than 26,000 times, and while fans gushed about how cute Theodore is, others noted that he looks just like his older siblings Arabella, five, and Joseph, two. 

However, some suggested that Ivanka's son should be sporting a 'Make America Great Again' cap to support his grandfather Donald's presidential campaign. 

On Wednesday, Ivanka was in Washington, D.C. overseeing the final touches on the Trump International Hotel, posing in front of the building for a photo she shared on Instagram that day.

Ivanka also posted photos from the day trip on Snapchat, including a picture of herself with chef David Burke, who will helm the kitchen at the hotel's restaurant BLT Prime.

'Hanging out with chef David Burke in his new kitchen... Almost done!' she wrote on the photo. 

The mother-of-three looked comfortable yet elegant in a breezy white linen dress, leaving her blond hair pulled back off of her face.  

It has been a busy week for both Ivanka and her three kids, who joined her at her Trump Tower office on Tuesday afternoon.

Ivanka made sure to capture snapshots of Arabella and Joseph working diligently at the pull-out desk in the kids' area of her office. 

And while Theodore may have been too small to enjoy the kids' area in the office, it is safe to say he had just as much fun hanging out with him mom's team in the conference room.

'Theodore weighing in on important topics,' she captioned a photo that sees him sitting on her lap while she and Arabella chatted with two of her employees.

The busy mom actually has two offices, one for her lifestyle brand and another for her role as the executive vice president of the Trump Organization. However, it is definitely clear which office Arabella prefers. 

Ivanka took to Instagram on Tuesday afternoon to share an adorable video of herself asking her eldest child what office she prefers. 

The businesswoman, who is wearing a white summer dress from her eponymous clothing line, can be seen leaning over and caressing her daughter's chin before asking her the all-important question.

'Arabella thank you for coming work with me today,' she tells her little girl. 'Which office do you like better?'

But before Ivanka can give her options to choose from, Arabella jumps in and says: 'Pink!' 

And while she may prefer her mom's 'pink' lifestyle office, Arabella most definitely has real estate development in her blood.  

The little girl happily donned a hard hat and carried a shovel as her mom filmed her singing, 'Heigh-ho, heigh-ho we're off to work we go'.
