Hilary Duff Spotted Adorably Sucking on Sleeping Son's Pacifier

Actress finds a cute way to free up a hand while running errands in Los Angeles

Hilary Duff may have her hands full. But in a really good adorable way.

The 25-year-old actress was spotted out and about Los Angeles on Tuesday as her sleepy 1-year-old son Luca opted to rest his tired head on mommy's shoulder.

(Go ahead and take a moment to verbalize an "aww.")

At one point, though, Duff found herself having to retrieve her car keys from her purse.

In need of a free hand, but determined not to disrupt little Luca's slumber, the new mom decided to simply pop the boy's pacifier in her mouth.

(Feel free to verbalize that "aww" again.)
