Jessica Alba and Cash Warren rang in 2018 in a BIG way this year—at the hospital with their new baby boy, Hayes Alba Warren. She shared the exciting news on her Instagram account on New Year’s Day, adding that her two girls, Haven and Honor, are already “obsessed with their new baby bro.”

Hayes’ arrival was a few days early, but for the family, it was the “best gift to ring in the New Year!! Cash and I feel so blessed.”

That joy is shared by hubby Warren, who wrote the sweetest announcement on his own Instagram.

“Your mamma is the strongest woman I know… you’re so lucky to have her by your side,” Warren says. “You have two amazing sisters who already adore you and I know you’ll be thankful to have them guide the way.”

With older siblings, Honor, 9, and Haven, 6, having a new baby in the household is sure to bring some changes—but it also means big sisters get to really enjoy their new role.

Warren continues in his post, “On your first day of life, I promise to love you, to cherish you, and to provide you with a sandbox full of dreams to explore.”

In the past, Alba talked openly about balancing motherhood with her career, saying that being a mom has actually made her find and live out who she is. And baby number three will surely only add to that revelation found in being a mama.

Welcome to the world, Hayes!
