This does suck! I'm so sorry. It's so nice when we get good parents and good kids and everyone is getting along and our days go so smoothly. Now, you'll have to start all over again with a new one. It's really unfortunate.

I have the opposite situation. I just gave a client 3 months notice because I have babies coming in and I'll be over ratio if I keep her. It came as a huge shock to them, and there were even tears this morning (hers, not mine)

it's just part of the business, the sucky part of the business.

I hope your next client is even better then this one!
