Jessica Biel and Justin Timberlake rarely ever post photos of their son Silas, so when they do, it's pretty much the most exciting thing ever.

The 33-year-old recently reposted an adorable pic of her holding her baby, and while you can't see his face (womp womp), you can see his little feet and we're shocked by how much he's grown!

The snapshot was originally posted on theSkimm's Instagram account, along with a Q&A with the actress, in which she revealed her morning routine with Silas.

On @theskimm Well good morning @JessicaBiel. UpWiththeSkimm #SkimmLife Name: Jessica Biel Job: Mama Bear, actress, producer, wannabe alpinist, consummate student of the @WomanCareGlobal #ThenWhoWill campaign. What time do you get up? It varies but I would say always (2) hours before I’d really like to. How many times do you snooze? I’m not a snoozer. Never have been. Wish I was but I would never get up if I did. I do snooze periodically throughout the day during any sort of boring conversation. Do you snore? I don’t think so. And even if I did, my dog Tina snores so loudly that no one would ever know if I did. Thanks T. 3 things you can't live without in the AM? Yoga. Eating breakfast with my kid. Listening to Erykah Badu while I eat with my kid. We love her. Favorite line from theSkimm recently? “What to say to your niece who just found out about Santa? It’s OK. The Nazi Gold Train isn’t real either. What's your morning drink? Bullet Proof Decaf Coffee. Who do you let speak to you before coffee? Wait… is that an option? Complete the sentence: Woke up like this: Disheveled, running late, doing too many things at once and underperforming all of them; but pretty thrilled about mediocrity! Could be a lot worse, guys. A lot worse.

According to the bombshell, her mornings consist of "Yoga. Eating breakfast with my kid. Listening to Erykah Badu while I eat with my kid."

Too cute!
