I'd like to give notice to a family for a number of small reasons which individually aren't big but collectively are getting me down & I'm struggling to know what to say to the parents. Main reason is I want to reduce my workload in the holidays as it's impacting my family too much (I've got someone wanting same days/hours but TTO from September) but I don't want to just say this in case they agree to TTO as there are other issues I'm not happy with inc children being lovely but demanding & don't get on with mine or other mindees 
Any ideas or suggestions? They've only been with me 6 months so will undoubtedly be cross but I don't want to ruin either my reputation or our relationship as I will see them at school.
