Liv Tyler is one proud mama.
And why shouldn't she be? Baby boy Sailor is adorable: Tyler, 38, shared cute photos of her son in different outfits on Instagram. In one photo, Sailor wears a cat-patterned onesie; in the next two, he wears a more formal, rather sailor-esque getup.
"Our beautiful baby boy - Sailor Gene Gardner - 6 months old - so so sooooo in love and grateful," wrote "The Leftovers" actress.
Tyler and partner David Gardner welcomed Sailor on Feb. 11. Sailor joins Milo, 10, Tyler's son with ex-husband Royston Langdon and Gray, 7, Gardner's son from a previous marriage.
Gardner posted one of the same photos of baby Sailor, not long after sharing a photo of himself with Tyler, Milo and Gray on a raft on a lake.
Tyler isn't shy about posting photos of her family; she often posts pictures of herself with the baby, as well as pictures of Milo, Gray and Gardner. She posted a heartwarming photo a few months ago of Milo and Gray cuddling with their baby brother.
The Tyler-Gardner family members aren't the only people in love with little Sailor; Tyler posted a photo of "Leftovers" co-star and newlywed Justin Theroux kissing Sailor's foot just last week. Perhaps he's feeling some baby fever.
