Born on December 31, the #familyoffive thinks Hayes is the perfect present for 2018.
"Best gift to ring in the New Year!!" she wrote. "Cash and I feel so blessed. Haven and Honor are already obsessed with their new baby bro."
Poppa Cash Warren also posted a sweet pic of their newborn and revealed that Hayes arrived early.
"You showed up a few days early but we couldn’t be any happier," he wrote. "Your Mamma is the strongest woman I know ... you’re so lucky to have her by your side. You have two amazing sisters who already adore you and I know you’ll be thankful to have them guide the way."
