Olivia Wilde and Jason Sudeikis' son hates how they dress him.

The 'Tron: Legacy' actress shared a throwback Thursday selfie with 15-month-old Otis Alexander Sudeikis and husband Jason with little Otis wearing a white bear onesie with ears and smirking in a disapproving way.

Sharing the photo on Instagram on Thursday (16.07.15) the 31-year-old beauty wrote: ''#TBT to Otis developing his hatred for tiny bear suits. #futuretherapymaterial #winter2014 (sic).''

The photo is rare as the couple haven't posted many pictures with their son since he was brought into the world back in April.

The last one was several weeks ago, this time on Jason's account, where he shared an image of a giggly Otis struggling to stand up.

Commenting on his son's cuteness, the 'Horrible Bosses' actor said he gets his looks from his mum, but his smiling is both of them because ''we're really lucky''.

He previously told US Weekly magazine: ''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. And then him smiling is both of us because we're really lucky.''
