Grumpy bear! Olivia Wilde and Jason Sudeikis’ son, Otis, is not a fan of bear onesies. The adorable 15-month-old showed his disapproval in a seriously cute Instagram posted by his famous mom on Thursday, July 16.

“#tbt to Otis developing his hatred for tiny bear suits. #futuretherapymaterial #winter2014 [photo] by Dad,” the Rush actress, 31, captioned the family photo op from last year. 

Fast-forward to July 2015 and the first-time mom is still cracking jokes about their little one. “Escape artist,” Wilde captioned a photo of tiny Otis trying to make his way through a doggy door last week.

Otis is normally more upbeat, his dad, Sudeikis, told E! this past January at the Sundance Film Festival. 

“He smiles a lot. I would say any looks he's got going — I feel like he's a real cute little guy — that's Olivia's doing," the Horrible Bosses actor, 39, gushed. "And then him smiling is both of us because we're really lucky."

“He's surrounded by love 24/7 and 80 percent of it is female based," Sudeikis added. "So I think he'll turn out to be a really good guy. I'm excited to see who he is."
