Hilary Duff's little man is getting bigger every day, but he's still just the right size for cuddle time with his mom!

Yesterday Duff, 28, shared a precious moment with her 3-year-old son Luca on Instagram: a photo (below) of the two of them enjoying some sweet snuggles.

"Kid crushes my heart one cuddle at a time," the Younger star captioned the black-and-white snap in which Luca can be seen lounging in his mom's lap as she plants a kiss on his head. The best part? The little guy's belly is peeking out of his firetruck pajamas!

Even after her divorce from Luca's dad (professional hockey player, Mike Comrie) was finalized last month, Duff says that both she and Comrie remain committed to co-parenting their son.

"We have such a great kid, and we're both so obsessed with him," Duff shared with Ellen DeGeneres in January. "We are good friends and we laugh a lot and we have a great communication. We share stories and pictures when one is not with Luca. Yeah, he's great, we're great, and we just keep on trucking."

Just last week the actress shared a smiling photo of the three of them along with the caption, "We are so proud of this boy!"

Keep up the good work!
