N.B.
I do home childcare in MN...licensed, degree'ed in Child Dev and all of that. I charge $35 a day no matter what the age. I provide all meal components and activity items (crafts, etc). School age kids are more work to me than infants and toddlers. They say "I'm bored" all day long, as they are used to someone telling them what to do all day (now its time for Math, now its time for Art, etc).
Just my 2 cents.
