Little Cayden Wyatt Costner was born last month (May07) and the 52-year-old actor worries he'll die before the tot becomes an adult.

He says, "My fundamental fear is that I will die and someone else will have to raise my new baby.

"I fear I won't get to coach him in terms of what it is to be a man."

The Dances With Wolves star admits he's already struggling to keep up with his younger wife, 33-year-old Christine - when it comes to his parenting duties.

He reveals, "Sometimes I fake that I'm still asleep in the morning. My wife buys it, and she gets up to feed the little one."
