What a little cutie!  

Tiffani Thiessen and hubby Brady Smith both took to Instagram this week to share new photos of their adorable baby boy, Holt

The cute couple welcomed their blue-eyed addition just last month and it definitely looks like he's one happy guy -- just check out that lovingly gaze and coy smile in the photo above. 

"Smiles for Momma. #happybabyboy," the "Happyland" star posted with the candid snap. 

Thiessen and Smith -- who tied the knot in 2005 -- also share a beautiful daughter together, Harper, 5. The 43-year-old actor posted a second snap of his and the "Saved By The Bell" alum's girl feeding her baby brother. 


"'Mommy, Daddy, no help please, ok? I got it.' - Harper (Big Sis)," the "Young Adult" star captioned sweet moment. 

The longtime loves have had an exciting few weeks -- they also celebrated their 10-year wedding anniversary on July 9, just days after little Holt was born. Tiffani even posted a few wedding photos in honor of their decade-long marriage.
