Hugs to you.
What a mean dcm. I would be livid. And debating replacing them. I would close the whole day Wednesday, that way you can go get a root canal without the stress of daycare for the day.
Once things settle down, it may be time to reconsider your business relationship with that dcm. If you can't get over how selfish she was, then its time to let them go and get a new dcf that will appreciate you
