As my hubby is a teacher, I like to have teacher's children.

I charge a non-refundable two-week deposit that becomes their first two weeks of care.

I take 6-8 weeks off unpaid (minus Stat holidays) a year including two weeks at Christmas, March Break and a couple of weeks throughout the summer. That being said, I'm still open the rest of the summer. If teachers would like the summers off, they have to pay me the non-refundable two-week deposit, and $100/month for July/August.

I haven't had any issues yet, and they appreciate me 100%. You as a provider just have to stand your own ground.
