Keeping their eyes shaded from the sun, Liv Tyler and son Milo William, 4 ½, were spotted strolling in the West Village of New York City on Thursday.

The actress, 32 this week, recently joked that she has no need for an alarm clock when her little blond boy is around!

“Milo wakes up every morning at 5:30 or 6 — ping! — and so the hardest thing is the lack of sleep,” she says. “I beg Milo to try and snooze for 30 more minutes! Of course, when they’re up, they’re up!”

Dad is Liv’s estranged husband, rocker Royston Langdon.
