This article presents the readers' views on questions about the length of time children are in child care arrangements. For Ken Weslake of Australia, in an ideal world children would be happy at home interacting within a family dynamic. He argues that it is not a question of how long as much as a question of: why they are there?; What are they doing?; and How appropriate are the activities for the development and enjoyment of the children? Once these questions are answered, then a suitable time and program can be set up. According to Jane Scott of Canada, neuro-developmental principles and research indicate that children under three learn through interactive play and daily activities within their family grouping. She contends that structured learning in a "school" environment is not developmentally appropriate or effective for young children. However, Ping Ong-Coates of Singapore states that it depends on the quality of care and the program that is being offered. If the program is stimulating, then six hours can be a good amount of time.
