KIM'S BILLION DOLLAR BABIES

DELUXE CRIBS, LAVISH TOYS, DESIGNER CLOTHES, PRIVATE PLANES — KIM KARDASHIAN AND KANYE WEST’S KIDS ARE LIVING THE DREAM.

WHEN it comes to her parenting philosophy, Kim Kardashian tries to keep it real. She and hubby Kanye West “talk about it all the time,” Kim has said. “We try to be as grounded as possible.” But with Mom and Dad worth a cool $1.6 billion, there’s no denying that their brood — North, who turned 7 on June 15, Saint, 4, Chicago, 2, and 13-month-old Psalm — have a lavish lifestyle that’s definitely over the top.

NO EXPENSE SPARED

For starters, their $60 million Hidden Hills, Calif., estate doesn’t have just the requisite envy-worthy pool but also an entire playroom stocked with goodies, including a $137,000 Swarovski-studded rocking horse, a $12,000 toy Lamborghini and a walk-in arts and crafts closet.
