Well, I sent them an email stating that I was not happy with the direspectful way the mother had spoken to me. She has not responded (it's been two days) and the dad (who does pick-ups and drop-offs) hasn't said a word. This combined with the fact that their child takes way more energy than any of the others and I am worn out, has led me to decide to terminate them on Friday. I believe they are trying to find somewhere else to put her anyway and I don't think this parent-caregiver relationship is working anymore
