Hilary Duff is taking a stroll down memory lane.
The 33-year-old actress-singer took to Instagram on Wednesday to share a picture of her growing baby bump, as well as to lament the changing of her pre-baby body.
Duff announced in October that she's expecting her third child, her second with husband Matthew Koma.
"We are growing!!! Mostly me..." the star captioned a post featuring a very brief video of Koma rubbing her stomach.

Months later, Duff's stomach is quite a bit larger as the baby grows, and she's taken note of the change.
The star shared some content on her Instagram story showing off her toned pre-baby body.
"Would be lying if I told you I didn't miss this body," she wrote over a brief video clip of herself cooking.
Next on her Story came a selfie of the star wearing a brown one-piece bathing suit with a flat stomach.

"Particularly this one," she wrote, per images captured by Entertainment Tonight.
However, while Duff may miss the way she looked before, she's still pleased with her body today.
A third image -- another selfie with her growing tummy on full display -- was also shared.
"But this one is working hard and doing pretty cool things for our little/big family and I'm super grateful and excited about that!" she wrote over the final post.
Duff is already mother to two children: Luca, 8, and Banks, 2.
She shares banks with Koma, 33, and Luca with ex-husband Mike Comrie.
