Kylie Jenner's family is "over the moon" by the news that she is expecting

A source told Us Weekly magazine: "The family is over the moon! Kylie loves how close knit her family is and is thrilled to bring that to her immediate family. Kylie feels more prepared than ever to be a mom.''

However, another insider claims Kylie's family are worried she hasn't thought it through in its entirety.

They told People magazine: "Kylie is very naive. Spending time with other people’s kids is obviously completely different than being a mom 24/7. Kylie of course has no idea about all the hard work and sleepless nights.

"With Tyga, whenever things were good, Kylie said she wanted a baby.

Between spending lots of time with her nieces and nephews, and being around Tyga’s son [four-year-old King Cairo], she claimed she was ready. Her family would beg her to protect herself. They were very concerned. They still think Kylie is too young to have a baby."

It comes after a source claimed Kylie had "always wanted" to be a young mother.

They shared: "Kylie is doing well and is happy. Kylie always wanted to be a young mom. She may be young, but she's very maternal and has lots of practice with babies! She's a very hands-on aunt and was basically a step-mom to Tyga's kid. The baby will be very well cared for and so loved. Kylie is excited that her baby will have cousins close to her age too!"
