Tina Fey: 'Motherhood changes working life'

Tina Fey has revealed that her work ethic has changed since becoming a mother.

The 30 Rock creator and star, who has a 5-year-old daughter Alice with husband Jeff Richmond, told OK that she has become "more of a sympathetic human being" in recent years because she better understands the difficulties of raising a child.

"The biggest thing you realise when you have a kid is how many other people in your workplace are dealing with that," she explained.

"When you're single, you're like 'let's work 'til 10'. You don't care. Once you have a kid, you're like, 'Oh yeah, if I'm exhausted because my kid was up all night with a cold, so are ten other people'. It makes you more of a sympathetic human being."

However, Fey insisted that she tries not to offer unsolicited advice to her expecting colleagues, including 30 Rock actress Jane Krakowski who is expecting her first child later this year.

"I always try to hook them up with something like 'a good baby nurse' or little things, but I only weigh in if someone asks my opinion," she said.

"That's the best way to offer it. I'm trying to think of things we've talked about, like whether you need a Boppy or not. I'm like 'yes, you do need a Boppy'."
