Tired new dad Rod Stewart

Rod Stewart needs an afternoon nap to cope with becoming a father again.

The 66-year-old musician and his wife Penny Lancaster, 40, welcomed their second child Aiden into the world in February and the 'Maggie May' singer admits raising the tot and his older brother Alastair, five, is taking its toll on him.

He said: "I think the fun you have with the little ones keeps you on your toes and their innocence reminds you of what's really important in life. Just like a child, I do find I need the odd afternoon nap too."

Along with Aiden and Alastair, Rod has six other children - 48-year-old Sarah, who was raised by adoptive parents, Kimberly, 31, Sean, 30, Ruby, 23, Renee, 18, and 16-year-old Liam with four of his former partners - but insists he won't change his parenting style at all.

He explained: "I'll be taking him down the same avenue as my other boys, with trains and football. I look forward to Aiden and Alastair growing up together, being best buddies."

Rod and Penny are also taking care to ensure their marriage doesn't suffer as they adjust to having two kids under the age of five.

Penny explained to Britain's HELLO! magazine: "We're being honest with each other about how we are feeling. We went out for dinner together a week after I had Aiden. It was important that I was able to break away from him and go out with my husband and focus on being a wife."

Rod joked: "Parenthood has taken our relationship to a new love and understanding but I'm looking forward to a bit more attention when Aiden starts to sleep through the night."
