Ohio runs one ratio rule across both home types. Each child care staff member cares for no more than 7 children at one time, and no more than 3 of those may be under two years of age. The house limits then differ: a type B home holds no more than 7 children at any one time, a type A home no more than 14 with the under-two limit applied per staff member. That per-member phrasing means the whole-home infant figure moves with staffing rather than sitting at a fixed number.

How Ohio defines the age bands
Under two years of age (the operative ratio and group size band): 0 to 24 months
Infant: 0 to 18 months
Toddler: 18 to 36 months
Preschool child (three years old or older but not a school age child): 36 to open months
All children under six years old, counted in group size including the provider's own children and residents of the home: 0 to 72 months
Children six years old through fourteen years old who are not related to the provider (counted in group size): 72 to 180 months
Children six years old up to fifteen years old related to the provider whose care is privately or publicly funded (counted in group size): 72 to 180 months
Children fifteen years old through seventeen years old authorized to the provider for publicly funded child care (counted in group size): 180 to 216 months
Mixed ages in one room
Under two is the only numeric band the ratio rule uses. Ohio defines a school-age child by enrolment or eligibility for kindergarten or above and by being under fifteen, not by an age in months.
Real questions, short answers
How many children can one Ohio provider care for alone?
Seven, with no more than three under two years of age, per Ohio Admin. Code 5180:2-13-18(A)(1). The rule raised that figure from six effective July 1, 2026.
What is the maximum for an Ohio type A home?
Fourteen children at any one time, with no more than three children under two years of age per child care staff member.
Does Ohio publish a whole-home infant cap for type A?
No. The rule states the under-two limit per staff member rather than for the home, so the home figure follows how many staff are present.
