We’re in luck, because this ‘gram isn’t even the only photo of Luca that the 28-year-old has shared this week. On Saturday, the adorable kiddo posed for mom in a graphic tee, making a duck face with his lips. The 4-year-old posed in front of a mailbox that reads, “Teach peace." Mom captioned the post with a peace sign emoji.

We can’t get enough of this adventurous young family. Keep scrolling for even more cute photos of the mother-son duo.
