Katie Holmes Marie ClaireAlthough Katie Holmes has been busy promoting her latest film 'The Romantics' in NYC and filming 'The Kennedys' in Toronto, she's still making plenty of time for her family. But in order to keep it that way, she's not having any more children ... for now.

"Maybe in a couple of years, but right now I want to make sure I'm really there for Suri," Holmes says in the October 2010 issue of Marie Claire, on stands Sept. 14. "I'm the youngest in my family -- my closest sister is 5 years older than me, and the next one is nine years ahead of me, so I was a bit of an only child, and I liked it! I liked having all of my mom's attention, and sometimes I think I still do."

And life as Mrs. Tom Cruise hasn't lost its luster. "It's really exciting. Tom's as big at home as he is on the movie screen. He's so passionate about everything, whatever he's doing. When he's being a dad, he's right there; he's giving it his all. It's inspiring and it's fun. It's an amazing life, but we always remind ourselves of how incredibly lucky we are."
