"How is it that just four weeks ago I gave birth to this precious little soul? It feels like and [sic] eternity and then it feels like the blink of an eye," the red-haired beauty captioned the post.

"I know everyone says how fast these times fly by, and I get it. But I hate hearing it!!! It makes me sad in a way. It's also a lovely reminder to stay present."

The 36-year-old actress has been chronicling all of her mommy milestones on social media since welcoming Lennox Sawyer with husband Kacy Lockwood, including his first hike and her first post-baby audition.
