They are in the hospital.

Hospital workers lined up outside the hospital for the big moment.
From ABC News producer Kaitlyn Folmer outside the hospital in London:
Time check: It's 1:48 p.m. EST and 6:48 p.m. BST (in London). The baby was born at 4:24 p.m. BST on Monday, so it is just over a day old.
Officials give five minute warning to reporters that the royal couple and baby will soon be leaving the hospital.

Doors open and crowd goes wild, only to be disapointed.
There they are. Kate in a light blue dress holding the baby. Prince William in blue shirtsleeves, waiving to adoring crowd.
Baby swaddled in blanket lifts little hand as if to wave to crowd.
"He's a big boy. He's quite heavy. We're still working on a name," Prince William tells crowd.
"Any parent...will know what this feels like," says Kate.
"He's got her looks, thankfully," says William.
"No, no, no," says Kate.
"He's got more hair than me," says William
