Los Angeles, Actor Hugh Jackman says he was a "fearful" child and was particularly scared of the dark.
"The Wolverine" star has admitted that when he first became a parent to his adopted children, 14-year-old Oscar and 8-year-old Ava, with his wife Deborra-Lee Furness, he didn't have any idea how to be a father and thinks it's because he was an anxious child who had various fears, reports contactmusic.com.
The 45-year-old said: "I was surprised how little my own parenting instincts kicked in. I was a bit of a pain in the a** at first, insisting he couldn't have a bottle straight before bed because I'd read up on it.
"My own mother finally said, 'Look, you may have read a lot of books, but the kid (Oscar) hasn't, so put them down.' But I was quite a fearful kid myself. Heights, the dark..."
He also admits he even incorporated a fear into his "X-Men" character Wolverine because he didn't want to play someone who isn't capable of feeling scared.
