A source tells PEOPLE, 'She knows she can’t rely on [mum Kris Jenner] every day and hired some help for the baby.
'Kris is helping out as much as she can, but she also runs a business and has her own life.'
The insider adds that the 20-year-old mum is feeling 'great' and has been enjoying leaving the house for short outings.
Jenner has been seen outside her home on two occasions since Stormi’s birth: for a friend’s baby shower on Sunday, and with BFF Jordyn Woods in L.A. Saturday, where they were photographed getting out of a black SUV.
The Kardashian insider explains why the new mum's tune had changed.
'At first, she only wants Kris and her sisters to help with the baby,' the insider explained. 'She is worried about new people around the baby.'
Of Jenner’s boyfriend Travis Scott, a source revealed to PEOPLE after Stormi’s arrival, 'Travis is able to do his own thing during the day as well, but he helps Kylie out at night.'
