We're having a major "aww" moment. There are no words to describe Olivia Wilde's latest Throwback Thursday Instagram post other than "beyond adorable"!

In honor of #TBT, the actress known for such films as "The Lazarus Effect" and TV series like "House" posted a family selfie from December. The picture features Wilde along with her fiance, SNL alum Jason Sudeikis, and the couple's now 18-month-old son, Otis.

While it's indisputable they are a cute family, the real stunner of this photo is baby Otis, who's dressed in a fuzzy bear suit.

Let's be honest: How can you not swoon over a baby in a tiny bear suit? However, Wilde knows Otis may not be exactly thanking mom for posting the picture one day. Appropriately, she captioned the post, "#tbt to Otis developing his hatred for tiny bear suits.#futuretherapymaterial #winter2014."

Otis' pout in the picture says it all. It looks like he already wasn't loving mom's wardrobe choice.

Lucky for Otis, Wilde doesn't post too many pictures of him. However, we sure wish she did — especially when they are as cute as this one!
