Looks like the guest of honor got sleepy!

A day after Kevin Richardson revealed his second son had finally decided to join the party – Maxwell Haze arrived Wednesday morning – the Backstreet Boys singer took to Twitter to share a photo of the family’s newest addition.

Seen cradled in the arms of big brother Mason, 6, baby Maxwell manages to sneak in a snooze as both boys cuddle close with mom Kristin in the hospital bed.

“Blessed!!!” Richardson, 41, writes.

Born at 3:05 a.m., Maxwell weighed in at 9 lbs., 8 oz. and measured 23 inches long.

Richardson, along with fellow Backstreet Boys Brian Littrell, Howie Dorough, Nick Carter and A.J. McLean, recently stopped by PEOPLE for an exclusive performance of their new single “In a World Like This,” the title track of their upcoming album, out July 30.
