"Melania loves taking care of the baby," says Donald Trump (at home in New York City). "If we have more, it will be terrific." For now, Barron William, born 8 lbs. 8 oz., has their Fifth Avenue home all to himself – including a floor above his parents' bedroom, complete with nursery, kitchen, living room and quarters for a nanny and Mom.

"Sometimes I just think, 'Oh my God, this is my baby. I have a baby.' There's nothing like it," says Melania (in the nursery). Says Donald, "I love to feed the baby. Not because I have to, but just because I love it."

In the Trumps' $100 million triplex penthouse, gifts from friends – including a golden stroller complete with its own chandelier (courtesy of Ellen DeGeneres) and gazillions of onesies – greeted Barron's arrival. "It's fun," says Melania of the stroller. "It makes you laugh."

"He's a very good baby," reports Melania, who turns 36 on April 26. "He's not like a crybaby – he's calm, and it's fantastic."
