TV presenter Dannii Minogue, 40, is mum to two-year-old Ethan.
Talking to us, her joy in her son shone through. "Everyone said to me that two is an amazing age and I thought, 'what can be better than having a little baby?' But it is. They evolve and they start talking to you more and interacting and playing. He's really into his sports, so he makes me play.
I did anything to get out of PE at school so it's ironic now that I'm running around a park throwing a ball with my son.
Dannii also talked frankly about the constant work-life juggle, especially as a single mother. She separated from Ethan's father, Kris Smith, in April this year.
"I think every mum finds the balance really hard - it's what you hear every single mum say who is working, even if you have a nine to five, or you have a business like me that is in a different hemisphere.
"It's difficult and you always feel guilty when you leave them and go and work - but you just do. It's part of being a mum."
In the week that Deputy Prime Minister Nick Clegg recently announced Government plans for new mothers to share paternal leave with their partners, meaning a potential return to work after two weeks, Dannii said she would have struggled to go back to work so early.
I really wasn't ready to leave the house until four months after Ethan was born. Everyone needs a different amount of time because you never know how you're going to react physically and cope with it.
"I really think it depends what job you're in and how restrictive your job is and the pressures of the company you work for or you run, or even the pressures you put on yourself. It's hard when you work for yourself.
Tabitha, my business partner, is running the day-to-day business and I had my baby in the first year, she had hers in the second. Every day she was out of the office, who was there to run it? So that was an amazing pressure working for herself.
"It's pretty difficult, especially if you have made your way in your job that you're valuable to your company and they're going to want you back.
"I was having a conversation with another mum the other day and I said I did one day of work for something around three months, then I came back to London (to work on X Factor 2010) with Ethan at four months and that was full on.
"However much I worked - seven days a week - I had him with me the whole time, which most mums can't do. I had a dressing room so I could see him throughout the day.
"I don't know how I would have gone if I'd have gone back at four months and had an office and I couldn't see him.
"I wanted to feed him and I did up until seven months. I could do that because of the job that I did."
