All children in care at any one time are counted as being in attendance for purposes of complying with the regulations governing capacity, group size, and staff/child ratios. An operator may not enroll a child for more than 14 hours in a 24-hour period unless approved in advance by the office. An operator shall maintain written records of: Enrollment with the child's name, address, telephone number, date of birth, and dates and time periods for which enrolled; and Attendance by groups of children which indicate the dates of attendance of each child in the child care facility. An operator may enroll a child only if the office has given written approval for the facility to care for children of that child's age.
