How Iowa defines the age bands
12 months of age or younger: 0 to 12 months
24 months of age or younger (statute: 'Infant' means a child who is less than twenty four months of age): 0 to 24 months
Children not attending kindergarten or a higher grade level (status defined, not month defined): 0 to open months
Children who attend school; 'School' means kindergarten or a higher grade level (status defined, not month defined; fromMonths 0 is a schema placeholder): 0 to open months
'Child': a person 12 years of age or younger, or 13 through 18 with a developmental disability (42 U.S.C. 15002(8)); toMonths 156 = 13th birthday: 0 to 156 months
Mixed ages in one room
The registration category, not the mix of ages present on a given day, sets the ceiling. A category B home with one provider present follows the 8-child limits until the second adult arrives.
Real questions, short answers

When does Iowa require a second adult in a home?
Category B and C homes require the second provider when more than 8 children are present.
What ratio applies to an unregistered 5-child home?
