you just need to lay down the rules (politely but firmly ) with her....if she doesn't like what she hears she will look elsewhere and you will be off the hook, not by your choosing.. if she doesnt mind and decides to change her picky preference and understands she needs to pay for a full time spot because that is what your contracts state, you could have a good client on your hands. she may just need to understand you are the one in control, up to this point you have pretty much allowed her to make the rules...just let her know....1) your contracts clearly state Mon-friday = full time pay. (the child is taking a fulltime spot even if a few hours shorter per day) and 2) you feed the children by a set schedule not by each parents desires. point out to her that is how you get the day to flow properly. sometimes you need to remind parents their child is not the only one in care and IF you catered to all parents specific requests you would run yourself ragged. Good Luck! this one can be saved...your right you just need to get tough!
