She stated via People: ‘I think I’m still learning how to be a single parent…I should be used to it by now.’

Kardashian went on to discuss how, although she employed various nannies and a personal chef, she still felt as if her children looked to her as their primary caregiver.

‘It takes a village to raise kids, but at the end of the day, your kids only want you,’ she stated.

The entrepreneur added: ‘The struggles that my kids go through really have nothing to do with the amount of help that I have.’
