They grow up so fast!

Jessica Alba shared a new photo of her son Hayes Alba Warren on Instagram Tuesday to celebrate his two months of life. Posing on his very own personalized milestone baby blanket, the wide-eyed little one looked straight into the camera as he also modeled his mother’s Honest Company brand of panda print diapers.

“Someone is getting real big! #2monthsold #mybabyboy,” Alba captioned the adorable photo.

She and husband Cash Warren welcomed their third child on Dec. 31. Hayes joins the couple’s two daughters: Haven Garner, 6, and Honor Marie, 9½.

Alba has often shared mother-son moments on social media, most recently sharing a picture of her oldest and youngest children bonding as they fed the baby bottles.

As Hayes continues to grow into a little person, Alba is also getting ready to return to work, specifically back to acting.

On Saturday, it was announced that the mother of three will be starring in a spinoff pilot based on the film Bad Boys, alongside actress and friend Gabrielle Union, who is set to reprise the role of Syd Burnett from Bad Boys 2.
