Meanwhile, another source previously claimed that Kylie and Travis “work really well as parents”.

The loved-up duo actually split in 2019, before rekindling their romance amid the COVID-19 pandemic, and it’s recently been suggested that they’re “very streamlined” as parents.

The insider explained: “Kylie is very maternal, and Travis is also very paternal. They are both super engaged when it comes to family and work really well as parents together. They are very streamlined.”

The ‘Keeping Up with the Kardashians’ star – who previously dated rapper Tyga – has “poured her heart and soul” into raising their daughter and she’s relished the challenge of motherhood over recent years.

The insider added: “She has learned so much about being a mom in the process.”
