Last month I was in a similar spot! It's frustrating but it does pass.

I was out A LOT of money over the summer. I'd "reserved" a spot with just a deposit (will NEVER EVER EVER do that again), as I'd had a child who would be moving up an age bracket the same time this guy would start (I'm with an agency in AB, limited to ratios). Well what do you know, one of the dcps quits their job in July, so I'm out 3 months pay for the one turning 2 years, and 2 months for the sibling who was over my ratio-ed age, but it took me a while to find another to fill it. On top of that we'd planned 2 weeks of vacation, which not only made it harder to attract potential clients, but I also don't charge parents for my 3 weeks off/year. It was really stressful, but it did pass! And I learned a couple of valuable lessons, the big one being not to expect parents to be in it for the long haul. They can pull their kids whenever they feel like it and we just need to be ready to react.

Hang in there!
