Kim Kardasian West took over Kelly Ripa‘s hosting duties during Monday’s episode of Live with Kelly & Ryan and opened up about a mini beef between her little ones: Saint, 20 months, and North, “I don’t know if it’s because she’s the older sister. I don’t know what it is. I thought it was a phase. She does not like her brother and it’s so hard for me,” said the 36-year-old reality TV star. “She would get so jealous when I would breastfeed and all that kind of stuff,” adds Kardashian West. “And now, the phase isn’t going away.”
