Canadian actor Eric Mccormack and his wife Janet are trying for another child.
The former Will and Grace star, 44, is desperate for a brother or sister for his four-year-old son Finnegan.
MCCormack says, "I think that people in their thirties generally make better parents but so many of my friends are having trouble - myself included - as fathers get older.
"My son was born when I was 38. We're trying for a second child at the moment and when it comes I'll be at least 43. It's hard.
"It's that Woody Allen line about Charlie Chaplin having kids at 70: 'Yes, but he couldn't pick them up!'"
