Luca is growing up so fast…

The actress revealed her baby boy is no longer just bouncing, Luca is walking !!!

It’s only been 11 months since Hilary Duff, 25, gave birth to her son, but he’s already on the way to being a toddler.

“Well I officially have a walking baby on my hands!” Hillary tweeted on February 28.

Hilary added, “It’s hilarious…the wobble makes it look like he’s 3 drinks in!”

I just can’t believe baby Luca is already walking. Hilary is going to have quite a mess on her hands now that Luca is completely mobile.In an interview with Parade magazine Hillary explained how she chose her baby boy name. “We had the names Cruz and Luca on our list with some others and decided at the very last minute what it was going to be,” Hilary explained to Parade magazine shortly after Luca’s birth. “We just liked the way it sounded together.”
