Chris Pratt is hands down one of the cutest dads in Hollywood. The actor shared the most adorable video of his 3-year-old son Jack for World Prematurity Day yesterday on Instagram, and it will melt your heart. Wearing a green bucket on his head as a hat, the video shows the tot intently coloring as Pratt and his wife Anna Faris sing "Ding Dong the Witch Is Dead" in the background. 

If that isn't enough to make you adore the Pratt-Faris family, the accompanying caption will. To raise awareness about World Prematurity Day, Pratt shared some statistics on his account. "Premature birth is the leading cause of death in children under 5 worldwide. About 15 million babies are born too soon every year. Nearly 1 million of these babies die within the first month of life. Support #WorldPrematurityDay and join the millions of volunteers who support #MarchofDimes," he wrote alongside the too cute video (below).
