Raising kids is tough: Chris O'Donnell

"Batman & Robin" star Chris O'Donnell says raising his kids has made him realise that parenting is difficult and exhausting.

The 43-year-old actor, who has five kids with wife Caroline Fentress, stays with his family in LA and has established a successful TV career by starring in TV shows like 'NCIS: Los Angeles', reported Radar online.

"It is a chaos here. Saturday morning when I wake up. I'm just so exhausted. The kids are raring to go and there'll be a half-dozen sporting events on Saturday," O'Donnell said.

"It's a tough place to raise your kids and have them be grounded. I feel very fortunate to have been raised with Midwest values," he added.
