The actress was spotted with her son Luca in Sherman Oaks on Wednesday, as they made their way back from a play date!
And it looked like they both had one heck of a time!
We're glad this mommy-son combo are branching out, and are hanging out with other mother-son or father-son or mother-daughter or father-daughter combinations!
We imagine it must get pretty lonely if you're just by yourself and your kid. Especially lonely for your kid!
But Hilary Duff is on top of it. She's intent on making sure her son is the happiest boy in all of the world!
And she's done a pretty amazing job so far!
