Naomi Watts has her hands full after removing 3-month-old son Samuel ‘Sammy’ Kai — and his carseat! — from the backseat of her ride as she returns home to her NYC apartment on Thursday.

During a recent appearance on Ellen, Naomi revealed that choosing a name for her and Liev Schreiber‘s second son was difficult.

“We couldn’t decide, we literally couldn’t decide on the name until we got to the hospital. Even three days after! We liked both Samuel and Kai and we still couldn’t decide if we wanted to go Kai Samuel or Samuel Kai. It’s Samuel Kai now, and we call him Sammy. But that’s a bit of a baby name so we’ll probably [call him Samuel].”
