I am an experienced childminder and looking after a number of children. Unfortunately I have given notice to one family - I have too much on my plate, struggle to make everything fit and the child in question is challenging in terms of behaviour. The family is now trying to convince me to keep him but this is my business, my work, my (health, sanity, time...). Please help me find the right words to stand by my decision and not let their problems with finding an alternative childcare arrangement become my problem. I am giving them the required four weeks notice, and could have the child a couple of extra weeks if required. Please help!
