Now, less than two months after Preston, 48, delivered Benjamin on Nov. 23, the proud parents are showing off their little "miracle."
"He's given the house a renewed spirit and purpose," says Travolta, 56, who held Preston's hand during labor as their 10-year-old daughter Ella Bleu waited excitedly outside the room with actress Kirstie Alley, a close family pal.
These days, the Travolta home in Ocala, Fla., is filled with joy, lullabies from Dad ("A Bushel and a Peck," from the musical Guys and Dolls, is a favorite), readings of Good Night, Gorilla and hugs from big sister Ella. Best moment for both parents so far? Benjamin's first smile.
