"For the most part he does his own thing," Spears (with Federline and Sean Preston in June) says of her husband's debut album, due later this year. Photo by: X17

For now, though, she is content to indulge her pregnancy cravings. With Sean Preston it was pickles and ice cream; this time "ice is the main thing. Crunching ice and chocolate – oh my God," she says. "I'll get up in the middle of the night and I'll get a Hershey's bar, the real big ones, and I'll put it in the microwave and melt it and eat it. It sounds disgusting, but it's so satisfying." How much has she gained? "This one I think probably 40 lbs. With Sean, I gained so much. So much," says Spears, cringing. "Probably like 50, 60! Agghhh!"

By now life with "Poo-Poo," as she affectionately calls her son ("Boo-Boo, Poo-Poo, it changes all the time"), has settled into a happy routine. On a typical day at their Malibu home, "he gets up around 7 or 8, and we'll play in his room and then go for a walk," says Spears. "My backyard is like Disneyland! I have the kiddie playhouse and sand box, the pool and his miniature pool." Sean Preston's favorites? "He loves books. He likes choo-choo trains, anything with wheels. He loves Baby Einstein and the Wiggles." At bedtime, around 10, "sometimes I'll sing to him," she says. "I make up stories, too."
