Jessica Alba and Cash Warren certainly had an exciting New Year’s Eve! The couple, who revealed that they were expecting a baby boy back in October, have just welcomed the little one into the world. Alba shared the news — along with the sweetest pic of her newborn — via Instagram.

“Hayes Alba Warren 12/31/17 Best gift to ring in the New Year!!” the 36-year-old wrote alongside the photo. Married to Pair of Thieves founder Warren since 2008, and already the proud mom of two daughters, she added, “Cash and I feel so blessed. Haven and Honor are already obsessed with their new baby bro. 👶🏽💙 #familyof5”

In the pic, you can see the tiny newborn sleeping peacefully while swaddled in a hospital blanket. With a head full of dark hair, it’s clear that he takes after both of his parents.

When the Spy Kids 4 star first revealed the baby’s sex, she told her followers, “@cash_warren and I couldn’t be more thrilled to announce…👶💙” She then added the totally apt hashtags, “#officiallyoutnumbered #babyboy #cantwaittospoilhim #hugsandkissesforlife #soontobeamomofthree.”

As for his name, she explained to Jimmy Fallon, “It has to be single or double syllable, has to be an ‘H,’ and it also has to be a word. And it can’t be too weird, because, you know… like, a little unusual, but you know, what if they want to be a nurse?” Thus, little Hayes.

Congratulations to the happy family of five!
