Olivia Wilde took to Instagram today to share a cute snap of her fiancé Jason Sudeikis and their 1-year-old son Otis, and we can't believe how fast the little guy is growing up. The photo shows Sudeikis teaching Otis how to snap his fingers—the tyke sits on his dad's lap outside as he focuses in on the task at hand. "Snapping lessons," the actress simply captioned the picture along with a heart emoji. But this isn't the first adorable 'gram she's posted of the pair. Last month Wilde shared an image of Jason and Otis at that beach that showed off the child's beautiful blonde hair. See it below. Olivia Wilde and Jason Sudeikis Go Glam for Red Carpet Date Night
