Belarusian tennis star Victoria Azarenka has said that she puts herself second to her son Leo after she became a mother and admitted she finds it tough maintaining her work life balance.

"It's a tough struggle because it's all about him. I put myself second to be able to do that, and then trying to play on a high level isn't easy. I train when he sleeps; if that's 10pm or 6am, that's when it is, because I want to optimise my time with him. Taking that one extra hour to yourself to relax or go to the movies is a struggle because I remember what it's like to have free time. Every second I have, I want to spend it with my son [Leo]," Azarenka told Tennis World USA.
