Cost of care vs Age of child

[Play and Learn]

\I think the only time I would give a reduction is for children in school full days, the reduction is in that I don't charge them for the full day, but hourly their rate is higher.

Same here. Same price for full-timers, any age. BUT parents supply the forumla and baby food if needed.
School agers are a different price as I probably only have them up to 2 hours max a day!

My rates are as follows:
Full-time ~ $35/day
Part-time ~ $25/day (less than 4 hours)
School-Agers ~ $20 before and after school or $10 for before, and $10 for after school.
