 This same poster was also referred to in Prime Minister Lee Hsien Loong's 2008 National Day Rally speech.Many other posters from the "iconic" campaign included similar themes of being content with two girls, to combat the common trend in developing Asian societies for families with only daughters to continue "trying for a boy".In addition to promoting just having two children, the government also encouraged individuals to delay having their second child and to marry late, reinforcing the inevitable demographic transition.
