Cat Deeley would love more children but has been told by doctors that she is "triple high risk".
The 40-year-old television presenter wants to give her and husband Patrick Kielty's 16-month-old son Milo a sibling but she has been told by doctors that her age is putting her at higher risk.
She said: "I would love some more. But I have got to get on with it if I do. When you go for your check-ups they call you a 'geriatric mum'. That is the terminology they use, I swear. They say, 'Ma'am, you are triple high risk.'"
However, Cat loves being a mother to Milo and likes to stay up all night to check he is doing alright.
She added to the Daily Mirror newspaper: "I am awake all night listening out for him. I am checking he is breathing. I am depressed I will never sleep again."
Meanwhile, Cat previously admitted she is too much of a "worrier" to have more children.
Asked if she will have another child, she explained: "The thing is. I'm a worrier. What if something happens? I do want more kids. I love kids. But I really didn't enjoy being pregnant and mine was easy. I was very wary of everything."
Cat and Patrick tied the knot in September 2012 after less than a year of dating and whilst Cat admits things happened "very quickly", she felt it was the best thing for them because they were both older and more self-assured.
She shared: "It was quite knock-your-socks-off for both of us. There were no more games and it all happened very quickly because we were older and comfortable in our own skin. A lot of our friends knew it would happen before we did but I honestly had no idea. Otherwise I wouldn't have wasted so much time. And thank God he happened to be around and that I hadn't missed him in the process."
