Final answer:
It is true that in family child care, operators' own children under age 7 are counted in the group size when present, to maintain safety and adequate supervision.
Step-by-step explanation:
In family child care, it is true that the operator's own children under the age of 7 count in the group size when they are present.
This is because regulations often stipulate a maximum number of children that can be supervised by a single caregiver to ensure safety and adequate attention for each child.
Including the operator's own young children in the count helps to maintain a manageable childcare environment and fosters better quality of supervision.
