With a quiet disposition – and a head of hair that lives up to the family mane – Donald Trump's first grandchild, Kai Madison Trump, makes her debut in the new issue of PEOPLE. The daughter of Donald Trump Jr., 29, a vice president at the Trump Organization, and his wife, model-actress Vanessa, 29, was born May 12th and weighed in at 6 lbs. 14 oz. "The baby is really beautiful," says Trump Sr., 60. "I've never seen such hair on a baby in my entire life. Just an absolutely beautiful baby, and healthy and happy, so I'm thrilled."
So what would Donalid like little Kai to call him? "Anything but grandpa!"
