For the snap, the Oscar winner wrote:
The actress was spotted with her son Luca in Sherman Oaks on Wednesday, as they made their way back from a play date!

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!
