In the heartfelt music video for her brand-new ballad “Acróstico,” Shakira emphasizes her love for her kids.

Last week, the singer released the tune just in time for Mother’s Day.

The poignant open letter “Acróstico” is written to her two children Milan and Sasha, who are also shown in the video. The majority of it is spent with Shakira sitting at a piano, with occasional sequences cutting to shots of their home: A playroom covered in Legos and other toys, a bathtub full of rubber ducks, and shelves lined with family photos.

Soon after, Milan and Sasha can be seen playing the piano with their mother. They even sing the song’s coda to her as they play, surrounded by their home’s packing boxes.
