Some sides of parenting aren't so sweet.
So says soccer stud Cristiano Ronaldo, 25, who opened up to Spanish sports daily Marca for the first time about six-month-old son Cristiano Jr.
"Of course I change the nappies," he says of the tot, whose mother has never been identified. "It's not the thing I like best in the world, but I do it."
The athlete — who also says that he may wed his girlfriend, Russian underwear model Irina Shayk, 24, "one day" — adds that he's already looking ahead to his boy's future.
"I would love him to like football for him to be my successor, but we'll see what happens," says the Real Madrid star, who signed a $132 million contract with the team in 2009. "My son will be whatever he wants."
But Ronaldo, who's raising the tot with the help of his mom and two sisters, says he's already shown a love for the sport.
"My son goes to sleep early, but my mother told me the other day, while we were playing, he was crying without stopping and didn't want to sleep until I scored a goal," he tells the mag. "I scored and five minutes later he was asleep."
