Raising 15-month-old son Aleph is a full-time job for newlyweds Natalie Portman, 31, and Benjamin Millepied, 35.

"Natalie is being superchoosy about her projects and taking more time off from acting," says a source.

The break from work definitely suits Portman. "She has this glow about her these days," says the source. "There's been a change in her since the little man arrived. She and Benjamin are so content."

The happy family-of-three were photographed enjoying a relaxing beach vacation in Turks and Caicos last week. The trip may have been a delayed honeymoon for the couple, who tied the knot Aug. 4.
