Becoming a mom again fairly quickly may be a piece of cake for Hilton Rothschild, if September comments from mom Kathy Hilton — who says her daughter has taken to motherhood “like a duck to water” — are any indication.

“She’s unbelievable,” the proud mom said of Hilton Rothschild. “With my babies, if I wanted to go pick them up I would just go in the room in the middle of the night, but Nicky is very much on a schedule. This is nap time, this is tummy time, so I’m just kind of like, ‘Okay.’ ”

“I’ll tell her certain things, but she’s read up on everything,” Kathy added of her younger daughter.

Another family member the new baby can expect to be doted on by? Aunt Paris Hilton, who threw her sister a lavish N.Y.C. baby shower preceding Lily’s birth and told PEOPLE in September that she’s “obsessed” with her niece.

“She’s literally the most perfect baby I’ve ever seen,” said the socialite and former reality star, 36. “She has these little angel lips and this cute little nose and these big blue eyes.”

Daily Mail was the first to report Hilton Rothschild’s second pregnancy.
