I am a single mother of a two and a half year old girl. I have had serious trouble with my daughter's last sitter, thus I am seeking a new one now. I know how important it is and comforting to have someone like yourself who goes to the extra effort with baths and things. I have had some sitters give my daughter a bath after she was out playing in the dirt or was feverish or something. The thing is, this is totally not your responsibility. As much as you may care for these children and while they do provide income for you, you do have other prioritites and responsibilities. You cannot just let them show up whenever they want without having a routine schedule and without letting you know. I would imagine it is not fair to you or the other kids you watch to base your day off of their schedule while playing a guessing game of whether or not they will really show up and when.
Besides their inconsistant schedule, these parents clearly aren't taking responsibility for even keeping their kids clean or fully dressed. Heartbreaking, really. However, my advice has to be that you have to look out for yourself and the other kids, so you may just have to tell these parents, as hard as it may be, that you just cannot watch them any more. If you must explain why and you bring up the inconsitancy and everything, be careful not to let them talk you into keeping them - or convince you that it won't happen again.
This sounds like a toughy! I wish you the best of luck!
