Scott Disick believes the best part of fatherhood is watching his children grow up.

The 31-year-old reality TV star finds it "breathtaking" seeing his two kids, Mason, four, and Penelope, 23 months, whom he has with his longterm partner Kourtney Kardashian, develop little traits as they grow older.

Speaking to E! News, he said: "You know, just watching your kids grow is pretty wild. Seeing yourself in them everyday. It's pretty crazy. Seeing a kid grow right in front of your eyes is kind of breathtaking, you know?"

Meanwhile, the hunk is set to welcome his third child into the world in December with Kourtney, 35, and is planning to have even more children in the future as they are both keen to have a big family together.

A source said previously: "It [the pregnancy] was planned. Kourtney wants to have a handful of kids."

Another source added: "She is only a few months along."

The couple, who have been dating since 2007, are said to have decided not to find out the gender of their unborn tot.

An insider said: "They don't know the gender yet. They just want the baby to be healthy."

The brunette beauty recently credited prioritising with helping her balance work and family life, and said her kids will always come first.

Asked how she juggles her schedule, she said: "Knowing my priorities. Nothing comes before my children. I find that putting everything else in order of importance also helps to get everything done."
