She's gotten a little mom time in. But two weeks after giving birth, Hilary Duff is busy doing errands for the baby, too.

The actress, 24, who welcomed son Luca Cruz on March 20, was spotted Sunday doing a little shopping at the The Pump Station & Nurtury in Hollywood.

Duff went with a sporty look with her outfit Sunday, perhaps not surprising, given that she's already hitting the gym post-baby.

"20 minutes on the elliptical seems like an eternity!!!" she Tweeted on Saturday.
