Ivanka Trump is having a pretty sweet weekend.

The 34-year-old mother of three posted an adorable photo of her very smiley baby, 4-month old Theodore James.

“pure sweetness #sundaymorning,” she wrote in an Instagram post showing Theo smiling from ear to ear in a matching set of khaki shorts and a shirt.

Theo seems like one happy baby, as the proud mom also posted a video of her little boy giggling uncontrollably on Friday.

Trump has three children with husband Jared Kushner. They are also parents to son Joseph Frederick, 2 1/2, and daughter Arabella Rose, 5.

Before her family-filled weekend kicked off, Trump ended her week with a quick workout, and posted a clip from her Friday training session. In the video, Trump performs some dynamic lunges.

“Quick workout in before the #weekend. #FitnessFriday,” Trump wrote in an Instagram post.

Last month, Trump opened up to PEOPLE about her priorities as a working mom, and said she adjusts her workouts to ensure that she maximizes her time with family.

“I want my children to see me first every morning, so I wake up at 5 and make sure to shower and exercise before they get up,” she said of her morning routine before prepping breakfast.
