On second thoughts, I am with Suresh on this issue.
Bringing children to tournaments is permitted and should be utilized. If opponents are not disturbed by the grunts of Azarenka, Sharapova, Williams, Nadal and Djokovic, they should not be disturbed by a 2-year old either.
Professional players in other sports are required to concentrate on their game despite tens of thousands of hooligans trying to distract them. If basketball players are expected to score free throws beyond these distractions, tennis players need to get tough - http://guycodeblog.mtv.com/2011/02/1...in-basketball/
As for the fans seated nearby, if they have a problem with the children they can opt to watch the match on TV from the comfort of their couch. No wonder interest in tennis is on the decline among children.
