An adorable toddler has tragically died after falling from a hotel window in South Dakota.

Madden Hein, 1, fell from a third floor window at the Club House Hotel & Suites in Sioux Falls on April 13 at about 9am, according to police.

The boy, from Minnesota, was staying at the hotel with his parents and was taken to a local hospital after the fall.

Kathryn Hein, the boy’s devastated mother, announced on Tuesday that her ‘sweet boy’ had died and shared on Facebook a picture of her and her husband Alex holding his little hand in the hospital.
