Ivanka Trump celebrated the birthday of her youngest child with husband Jared Kushner by posting adorable pictures of the 1-year-old on Instagram on Monday.

Theodore James Kushner turned 1 on Monday, and was treated to spaghetti, a Kushner family tradition, and a lovely cake baked by the family. Ivanka took to social media to express her love for her youngest child in a post captioned, “One year ago today, little Theodore was born, expanding both our family and our hearts! This little boy is pure sunshine! Happy birthday baby boy!”

Ivanka, 35, moved to Washington, D.C., from New York earlier this year after her husband was appointed as a special adviser to her father President Donald Trump. The couple has moved into the posh Washington neighborhood of Kalorama, which boasts of a number of other high-profile neighbors including former President Barack Obama.

Theodore was born when his grandfather was still over two months away from the Republican nomination for president. A frequently appearing face on his mother’s Instagram, the young Kushner’s first attempt at crawling was captured at the White House, a big milestone for the family.

Theodore has two older siblings. Arabella Rose Kushner is 5 years old, while her younger brother Joseph Frederick Kushner is 3. Ivanka also posted a picture of Arabella holding Theodore’s birthday cake on Instagram on Monday.

The first daughter took her three children out to the Smithsonian National Zoo over the weekend, and posted a picture with an elephant on Instagram. Ivanka and Kushner also took a mini winter vacation earlier this month, when the whole family flew down to the ski resort town of Aspen, Colorado.

Here are some adorable pictures and videos of the youngest Trump-Kushner child:
