The hills are alive (and singing at the breakfast table) in Ivanka Trump's home this morning. On Thursday, Trump's 2-year-son, Joseph Frederick Kushner, was very much in a musical mood as he belted out a pajama-clad rendition of "My Favorite Things" from The Sound of Music. While Mama Trump seemed to enjoy her tyke's a.m. performance, older sister Arabella Rose Kushner, 4, was not a fan.

Standing just behind her little brother, Arabella made a point of plugging her ears to drown out his noisy anthem. Joseph, however, didn't seem to notice and continued on with his happy tune as Trump stood by to capture the scene. In captioning the video (below), the proud mom wrote: "Breakfast concert series."

Frequently posting morning Instagrams of her kiddos, Trump takes time to cherish mornings with them before heading off to work. Last week, she shared the cutest video of her 2-month-old, Theodore James Kushner, letting out some serious giggles.
