The `Revolutionary Road` actress devotes so much time to her children - 10-year-old Mia, her daughter with first husband Jim Threapleton, and seven-year-old Joe, her son with second spouse Sam Mendes, who she split from in March 2010 - she has joked she has forgotten how to "sit down", and has to force herself to make time to just relax.

She said in an interview with Britain`s HELLO! magazine: "Any mother knows the last person you think about is yourself. I`ve been a mother for 10 years and I`m still trying to figure out how to give time to myself without feeling guilty about it.

"Sometimes I`ll sit down and I`ll go, `Oh it`s just nice to sit down,` because truly, I`ve forgotten how to do that.

"You forget to sit down and not worry about what needs to be done for the kids, just take time for yourself and pick up a book or read a recipe. I tell myself `Just ? Sit ? Down` it`s a challenge."

Kate, 35, also revealed she is enjoying her 30s and feels much more secure in herself and prepared for the challenges of life than she did in her 20s.

She added: "I think that for a lot of women, our 20s are a time of really figuring things out and figuring out what we`re really about. Of course, at the time, we think we know exactly who we are, we think we`ve done all the growing emotionally ? And then along come our 30s and it`s all different again.

"I`m really enjoying my 30s, actually. I have so much more life experience than I did when I was 25 and that`s a real luxury."
