The 17-year-old says that her elder sister Kim won't let her take care of the little girl on her own,reports femalefirst.co.uk.

Kylie said: "Kim doesn't trust me like that."

Kim and Kylie are often compared because of their similar physical appearances but Kendall insists she is "completely different" to the 34-year-old star.

"When people say, 'Kylie is exactly like Kim', they don't really know me. We're opposite sides of the spectrum. We're completely different," Kendall told Britain's Grazia magazine.

While Kim may not trust Kylie to babysit North, she clearly has more confidence in some of her other siblings, as it was recently revealed her sister Khloe Kardashian, was named as the toddler's godmother when she was baptised in Jerusalem earlier this week.
