Three-time U.S. Open champion Kim Clijsters says she may play for another four years.
"So as long as it's all going well and [our daughter] Jada's not obligated to go to school we'll try to keep it going," Clijsters told the Daily Telegraph. "But if the family is not happy living this lifestyle then it's an easy choice for me to hang them up."
The 27-year-old Clijsters, who is married to former basketball player Brian Lynch, saays that being a mother has rounded out her life.
"I think in any girl's life [motherhood] makes a big difference and it has the same in mine. I really feel I have a good balance and I feel that is the most important thing."
